My little Honda blew the the exhaust pipe off and they were able to fix it easy peasy. They were very nice to me and got me back on my way quickly that morning. If I ever need exhaust work I’m going back to them. Thanks again!

I went to Collins muffler to get some exhaust pipe for my garden tractor so I could run it out side the hood and then above the hood .Clayton had exactly what I needed he did a little cutting and bending and a little prefab on the pipe to help me out so I could take the pieces home and weld it together thanks Clayton appreciate it I would recommend anyone to go to Collins muffler for all their exhaust needs I will definitely be back .

Nothing but good things to say here. The guys were quick, they got me right in on my appointment time and did a nice job welding up my aftermarket muffler even with a tight clearance to weld it in. Fantastic work.

I am working on restoring a 69 jeep gladiator and they gave me an excellent price on pipe and even fixed my botched welds when I tried putting it together. They didnt charge me to fix my buggered welds and the pricing is phenomenal for pipe. Everyone I have spoken to in here has been friendly, knows their stuff and are easy to work with. I am a very happy camper

Collins muffler was amazing! They fixed a mess created by grease monkey, and then completed my oil change in a very timely manor, and for a more affordable cost than grease monkey! Needless to say I will bringing my vehicles to Collins from here on out!

Great service, I had some cracked exhaust headers that needed to be repaired, they were willing to take on the odd job and I had them back by the end of the day, they did a great job with the repair, thank you!

Super chill and knowledgeable guys had my exhaust welded up and had me on my way in about 45 min. 1992 jeep wrangler.

Great service, and reliably quick. I went in for i new bracket that holds my muffler in place. Came back within a half hour and problem had been resolved. Even took time to go over the logistical with me of the project. Overall awesome place and service.

Ive used Collins Muffler over the years numerous times and they are excellent with repair work and customer service. I was in on 04/09/2021 for some custom exhaust work parts I needed cut. They had what I needed and had me in and out. Efficiency and quality work.

I went in for an exhaust repair, told me they could get it done in 45 minutes and they were not wrong. Clayton and Jonny were professional and knowledgeable. The exhaust work was very clean, definitely satisfied with the work done on my Civic Si. Will definitely return and recommend. Overall amazing work and good customer service!

Love this place! They are so helpful and cost is reasonable. They do what they can to help us out every time.

I was well taken care of I will most certainly be back for other necessary repairs.

Quick service and very friendly shop. Went above and beyond explaining the options and what repairs needed to be done. My truck passed emissions after the new muffler and my wifes suv actually stops when you step on the brakes! Shop is kind of hidden around the corner so look where you least expect to find it!

The guys got me in right away. They welded a loose pipe back together and didnt even charge me! They have earned my loyalty and Ill be back when I need anything done. Highly recommended!!!

Top notch people at amazing price I was in and out back on the road in no time I would highly recommend them to anyone needing to get work done thanks Collins your the best!!!

I was really impressed with the guys there that did work on my car ! I was shocked how cheep I got my repairs done and started to leave without my keys ! I said I’m going to skip on out of here ! I was so pleased I left a tip for the men working, to let them know how much I appreciated them ! I had a dip stick that needed tack welded back on and they went the extra and did that for me ! I will be back because I need tie rods done now ! Easy to work with

I have been in twice to Collins Muffler and both times have been great. They have had professional and courteous customer service and got both jobs done quick for a great price. I highly recommend them and plan on going to them for my future exhaust needs.

The Crew at Collins Muffler are not only professional, but extremely virtuous and honest!! The shop owner is outstanding to deal with, and the Techs arr EXTREMELY knowledgeable about what they’re doing, and would not hesitate to return to them for future services.. Kudos to the Collin’s team!!

Fast service helped me with my suburu.

They are amazing!!!!!!! Very kind and professional I highly recommend them!! Totally worth stopping by and getting things fixed.

Best place for great customer service and best of all no BS!!!! Trustworthy, honest and no nickel and diming!!!

Perfect place for your. custom exhaust system & other smooth riding head corders shocks struts etc. good costomer service !

Told me my engine was blown and they would happily replace for 4k.. Turns out that a vacuum leak and torn spark boot mean the whole engine is dead. Im happy there are enough suckers out there to keep em open though.

These guys are great they treat my vehicle like it’s there’s every time!

Have been very satisfied with their service and skilled technicians.I would highly recommend them. They stand behind their business!

Always get thing done when they say they will and amazing quality definitely recommend to anybody who needs an exhaust fixed I honestly will never go to any other place for my car ever

I went for a rattle on my trailblazer and they found the rattle and a exhaust leak. They fixed the rattle and took care of me ! I’ll definitely come back for any exhaust needs !

Great customer service and timing on working on my vehicles

They gave me all the info I needed, and reasonable price quote. Helpful representative over the phone.

Quick in and out service. Very professional explaining in detail the repairs. Great job guys.

Stellar service. Called a day ahead of time and set appointment. Even though they were full when I arrived for appointment, they worked on it right when I arrived. I have a Frankenstein of a van (nothing is original parts) and they manufactured a solution right on the spot. I was shocked at the price. This almost never happens: their price was so low I couldnt believe it. Yeah. Low. Like way lower than I expected. Ive been in before and thought their service was good. Im a customer for life now.

Super helpful shop!!! Thank you!!

Went in to get a quote on a new muffler, and 45 minutes later left with a new magnaflow muffler and tip. looks great, good looking welds, these guys know what they are doing and really seem to like their jobs. Side note, it was cool to listen to them exactly point out the issue with a vehicles exhaust problem, only by hearing the sound it made when pulling in, and being exactly spot on. They have my business for life.

I appreciated the way everyone was so kind, helpful, and honest. My visit was quick and simple and I appreciate that they are a part of the BBB. They explained my options and quickly fixed my repair. Thank you!

They were fast and honest let us watch as the work and even stayed past hours to finish the job! Trustworthy for sure!

Got our car in on short notice and their pricing was extremely reasonable for welding in a new flex pipe. Thank you!

Great service, great price, highly recommend! Clayton and the team got me in and out under 45 minutes and had multiply eyes on my project making sure everything was aligned and nothing was missed. I will be back with future projects. Fair and honest to meet my needs.

They extracted one broke off passenger side exhaust manifold stud and replaced the warped manifold. Charged quoted price!At time of quote I was told this is a common issue and it happens because the OEM studs fail. I was told that they would install a new manifold, new studs and gaskets at connection that were taken apart. When I picked the truck up I popped the hood and noticed that they reused the studs. I ask why and he said that the parts store only had a few.After I returned home I crawled under the truck and first thing I see is a new weld on the exhaust pipe coming down from the manifold.This is completely unacceptable. I talked with 2 dealer service centers and 2 other small shops all the prices were about the same.I picked Collins because they’ve been around for as long as I can remember! But apparently that doesn’t mean they do the job correct.Just because you have the ability to cut something off to make the job faster doesn’t mean it’s the correct way to do it. If they are going to cut corners then they should not be charging the same price as the guys that do the job right.

Collins has been at this location for 30 years due to good service & consideration for the customer !

My alternator was dying in my 2006 Buick Rendezvous. I bought a new alternator and my son attempted to put it in but couldnt. Collins was happy to install my new alternator (other places would not). They did it right away, charged a fair labor cost and had it done within a couple of hours. I highly recommend this shop.

On Tuesday I took our pickup in for a new tail pipe. Joe offered great customer service by explaining that they found out the muffler was also compromised. The price offered was a good value. Joe and his boss actually worked together to make the job quicker to help me keep the appointments I had previously made. We are thrilled with the work, the value and the service!Cristi

Took care of my shelby very well, quick and friendly definitely would recommend and return🔥ps there’s a doggo that’s greets you at the door, he’s pretty dope too

Generally I come on here to vent and eviscerate some shady merchant that Id like to see go down in flames. This is not the case with Collins Muffler. Here is why, these guys are HONEST mechanics not interested in ripping people off. I know, you may find it hard to believe. Finding an honest mechanic is like finding an honest spouse or business partner, once youve got them, you never want to let them go!I was in there this afternoon after having troubles with one of my vehicles, certain that I needed at least a new starter and possibly more. Not the case, upon their diagnostic check they found there was an issue with a sensor, they reset it, re-diagnosed to be certain, tested it and everything was gravy. The best part was they didnt charge me a dime! Nothing, nada, zilch! Not even for the diagnosis which they initially quoted at $99.00 and I had agreed to pay. Even better than that, I was in and out in less than 30 minutes.If you havent found your honest mechanic in this life, fret not, hope is alive, for now you have! These guys are the real deal and have gained a customer for life.

I went in to get my muffler replaced and these guys did a fantastic job. The customer service is phenomenal and they wont try to sell you something you dont need. Thank you for great service!

I took my truck here to get a new muffler. Customer service was fantastic and the price was even better. They got my truck in quick and I had it back the next day. I would definitely come back in the future.

The guys at Collins Muffler & Service were very helpful in identifying and fixing a rattle that had been haunting me for months. Their staff rallied around my vehicle and worked together to get me back on the road in much less time and at a much lower cost than I had expected. I really appreciate the great experience and look forward to working with them again.

Great people and service. Got my vehicle fixed fast and with a great price. I would recommend these guys to my family and friends.

The guys at Collins Muffler went above and beyond to take care of my vehicle. When the problem was identified, they found a difficult to find part on a Saturday, and fixed the problem. I am very grateful for the professional, personable approach they have, and the quick service they provided! Collins Muffler is now my go-to service shop!

Clayton at Collins muffler and service of Greeley helped me out with my exhaust and the service was excellent, Quick and done right. Would highly recommend to anyone needing exhaust work to work with them.

Found out my struts were leaking and the place that originally found the leak wanted 800 for everything. I dad recommend Collins muffler and they did amazing work. I spent less at Collins muffler than what the other place wanted and Collins muffler made sure I got the best price and that I knew everything was going on. I will be going back for further work on my truck and I know my family will be back as well. Very knowledgeable and very caring place. They take a lot pride into the work they do and very reasonable prices!!

Ive been doing business with Collins Muffler and Service for about 8 years now. They have done all the work on my vehicles. From a simple muffler to a transmission change,they have always done the for a fair price and in a timely manner. Im very happy with the services provided. If youre in the Northern Colorado area I highly recommend Them for all your vehicle services and needs. BTW Sean and Joe are some of the easiest going guys you will meet in the the business. They tell you like it is and dont try to up sell you. If I could give them more stars I would.

Bad bad experience not professional work didnt do as I asked tried to put two different color mufflers under my car. One exhaust tip is loose both are hanging at different levels not centered under my bumper. If you care about the look and quality of your car go somewhere else. Going to have to pay somewhere else to fix all their mistakes.

My husband is disabled and can no longer work on cars, we was looking for a muffler shop, Collins Muffler Shop was highly recommended. I am very pleased with the services they provided on my car. I received great customer service from Joe, and I will be returning such a great business!

Excellent shop! Took my 2014 Ram 1500 in for a muffler delete, was in and out in less then an hour with same day call in! Recommend this shop to anybody looking for a custom exhaust. Thank you guys again!

These guys are great. Great prices and very upfront and trustworthy!

Great place if you need help

After reading all the reviews on here I was a little worried about taking my jeep to Collins. I saw that the new manager was trying to better his quality of service so decided to give them a try. Ive waited three weeks to write this review and im still extremely happy with the work and service I was given. They were extremely professional with me, extremely affordable and I had an overall great experience. I look forward to taking my jeep back to them here in the near future for some more work.

Had a failing cat converter and these guys did a fantastic job with getting me hooked up at a great price and did awesome work on my Mustang. Theyve gained a customer for life and if I ever have any car needs Im going to these guys everytime. Best customer service Ive ever had!!! A+!!!

These guys ROCK. I had a horrible experience with another mechanic in town who put me through the ringer on my frozen brakes. These guys were honest with me through the whole process. My car is working wonderfully now and I was given a very fair price on all of my repairs. They were even kind enough to dig through the dumpster to show me my damaged parts so I would know what to look for in the future. These guys not only gave me peace of mind but also won a long time customer. Thank you!!

Collins muffler does a top notch job. They provide excellent service at a fair price. Highly recommend them.

I went in there for bad breaks they were very very helpful making sure everything was done right and fast! Very curtious to their customers making sure they are 100% satisfied with their results! I would recommend them to anyone over and over again! Will be back if I ever need anything done on my truck again! Thanks again for everything o yeah by the way the exhaust looks great!!

A firm handshake and a promise that my car would pass emissions after the work was done were enough for me to give them a try. They were on time, finished the work even sooner than quoted, and were more than fair with the price and even offered lower cost services that could help. Brakes are next, and I now know I have a mechanic repair business that I can trust.

Good

Recently my daughter and I moved to Greeley, from Metro Denver. Both of our vehicles needed a local mechanic. Her truck wouldnt pass emissions, and my old station wagon muffler got Loud, and sprung leak of antifreeze. We live down the street from Collins Muffler, and gave them a call for help.Perfect, got quick service appointment, examine truck first, great service in one day, and truck now back on the road and license plate renewed for another year. My old car went in next, easy find for leaking fluids and repair. Scheduled the muffler and exhaust to be next, as parts needed to be order. Very Pleased with work and service. Thank You

Prepared to be lied about the initial quote and to be charged triple what they say. Definitely way overcharge you. Bonus star because the people were polite.

We have had EXTENSIVE work done on my truck. The work was done well, in a timely manor, and most important, AFFORDABLY! Sean and his crew stand behind their work and have our business for these reasons! Thanks again guys!

Great service. I wanted a muffler put on. They gave me a quote ahead of time and had the muffler installed on my truck in no time. The price was fair and exactly what they quoted me.

If you want amazing service done to your car go to Collins muffler. They replaced my pulley and took great care of me. Wouldnt go anywhere else. Thanks guys youre amazing.

Ive brought my car in a couple times now, always quick with reasonable prices, plus all the guys in the shop are very nice!

Collins takes great care of me and my truck! I know Im getting quality repairs for a great price. The level of customer service is unmatched in Greeley.

What a great experience...the crew are top notch had a check engine light on they checked and explained what was wrong fixed problem ! Honest -Efficient-and Priced affordably.. If you have automotive needs give this company a call..5 STAR TREATMENT ⭐⭐⭐⭐⭐

Took my car in and thought I needed a new muffler. Turned out I just needed a few bolts tightened and they fixed me right up. They could have totally taken advantage of me and did not. They have a customer for life!

They dont just do exhaust work here, they do anything and everything, the guys running the shop are solid, honest guys, Ive heard some people complain about price but honestly you get what you pay for and these guys do amazing work, their work also comes with a nation wide warranty with the use of some program they called tech net which I thought was pretty neat!

I first started going to Collins Muffler about a year ago, and have to say they are great at letting you know what is wrong with your vehicle in a very timely manner as well as notifying you right away if they find anything that was not talked about before hand & always give you the price & time it will be ready....Joe the General Manager has one of the first honest mechanic shops Ive found in Greeley...Thank you for all the Great work and help you did on the car guys!

They have always done good by me... reasonable fair prices

Joe handled the dual exhaust jobs on both of our new vehicles very professionally!They look and sound great!!Thanks Joe.

Excellent service

Some of the coolest people you will meet and there work is top of the line. I will go no where else

The team at Collins Muffler & Service went above and beyond to help me get ready for my last minute road trip. Squeezed me in even though they were already busy and STILL got me back on the road same day!!!! They were also very friendly -great customer service!!!!!

Collins is my go to mechanic shop and the only place I recommend. They are experienced and knolageable, and everyone there goes out of their way to make your visit a pleasant one. So if you need a new kick ass exhaust or any full service mechanical repair for a car or a diesel Collins is your local neiborhood shop! Give them your business and youll never regret it!

Needed muffler repair and wanted to do a dual exhaust, but employee recommend I do single and ended up saving money... truck never sounded better.Thank You Collins

Im always happy with my service repairs and any upgrades that I have done on my vehicles. They also guarantee their work and if you have any issues they take of you like your family.

This crew actually took the time to understand my concern and problems with my exhaust. Downpipe and intercooler piping was slightly off due to manifold upgrade.Ended up with professional welds that will hold through high heat.The owner was there to introduce himself making it even more welcoming to the shop. Place was clean and presentable with a well maintained schedule with when their customers will arrive for services.All the work ended in a very rare cheap price.Already scheduled for more services!HIGHLY RECOMMENDED!

Always super friendly when I call and helpful when looking for parts.

Definitely the place to go if youre looking for honest service without over-paying.

A bout a month ago a clamp broke on my muffler and was hanging very low.I called the guys at Collins in Greeley and they told me they were booked up for the day. But to bring the car in and they would try and fit me in. By the time I got there it was 12:45. One of the guys I assume was on lunch break drove the car in raised it up and welded it up for all by 1:00. They charged $25.00 and I gave them a $5.00 tip. Great job guys.

Best shop around to have your custom exhaust built. And also a great place to have all your other services and mechanically needs taken care of.

Quality mufflers, professional installation, very reasonable price

Everyone at the shop was rude, from the time I called to make an appointment to the mechanic that looked at my car. All i needed was a simple fix to my light and they seemed like they didnt want to do it, giving excuse after excuse. I will never go back to this place unless they fix their attitude. The receptionist was rude and didnt even introduce herself.

Amazing experience all around!! Just perfect! Highly recommend coming here!

Anytime I have had a problem with my cars the service is great very affordable an timely they work with you an your situation I tell all people try there first Joe is very good person and the shop no problem they will do their darnest to help you out .

These guys are great! Very fast and friendly service and the price was right on.

Good service, affordable price extremely nice people, had a good experience overall

This place is awesome will go the the extra mile to make things right

With the numbers on my failed emissions test I never thought it would pass but the guys at Collins got her done. Great customer service!

I do alot of personal auto repairs, but I dont do exhaust sytems. The mgr at Collins was knowledgable and the staff perfomed my exhaust repair quickly and at the estimated cost. I feel this shop perfoms quality work for a reasonable price. I would definetly recommend and use them again.

The only place I trust with my truck. They have done a lot of work on it and have always been fair and honest.

They were awesome and nearly half the price of labor from comparable places..I highly recommend them!

Honest shop fair prices.would definitely give them repeat business!

Had my resonator on my 2014 Jeep SRT deleted and they did an awesome job even when I came back for one other small thing they helped me without question!
