They are Professional。 I like hereAnother shop install for me but they did reallybad job Everything lose and bad angelvalley muffler fix for me they are so good

This shop has been in and around the La Puente area for many years. They have been at this current location for about three years now and Im glad I found them again!! Theyre a great shop to use for general exhaust repairs, mufflers, and catalytic converters. They also have fabricated custom mandrel bent exhaust systems for my performance cars in the past. The owner and his sons do great work and are reasonably priced. I do recommend you call ahead on weekends as they do get busy.

Good and prices Quick Service employees are good okay care of you real quick if you need to get out of there real quick and right next door is interior shop so if you need an interior done

Professional, Knowledgeable, Friendly, Patient, Honest, Affordable. My catalytic converter was stolen so I went to a muffler shop in Covina and was quoted $1700. I looked up for another muffler shop and found Valley Mufflers and was quoted $700 less. The shop is family owned. Thank you Javier for your service.

Very helpful and nice people fixed my car right away and the right way definitely go

Good ppl and good prices with a great job...keep hooking us all up...

I luv these guys. Been letting them pipe my classic cars for 20yrs now. And they always do great work. Family owned, which I luv!!!

Great Service! Very Reasonable on Cost! Guys that work thereake.you feel like Family! Gracias Denisio!

I just walk in and ask what I wanted. The person that works there told me to bring it on the lift. He looked at it and gave me a reasonable price to weld on a pipe. He was cool to talk too. I will definitely bring my friend once he gets his GLADIATOR. I will be coming back also for any other exhaust in the near future. Thank you

Excellent service. I’ve been a happy client for 21 years

It was so nice jesse the owner was a generous man great job on my car

Theyll hook you up at a good price, and they do great work!

They are very knowledgeable and honest.

Ive been going to this shop for 20 years. Theyve done great with all of my vehicles.

Good job with my 1996 Honda Civic DX Non Type R.

Rude service from tony. was recommended by a couple of friends. Regret coming 🤦‍♂️

I have been following this shop for a long time,, I now heard they string moving soon.These guys are always accommodating, real great prices and experienced mechanics.Dionisio, the alpha male is always friendly and offers the best advice and service..I recommend this place.It should be a 5 star, I guess they are too busy to organize the office at the and of the day.You will always come back.

This place is amazing. Called and got a quote over the phone. Took the car in to make sure the part was correct. They ordered it and had it done quickly. All in the same day. Other places had told me the part would take one day to get there. Great price and service. This is a great shop.

I have know the owner dionicio for many years,always great service.not to mention the best prices in town.strongly recommend.

Good quality service for decent price

Handled my issue real quick. With a low car, I know Ill be back again. Thanks again!

Good service

Its a Father and Son business for as long as I have known and they are great honest very knowledgeable Men.

Jr and his dad are awesome! Very friendly and knowledgeable staff.

I called the day before to ask what it would cost to have my catalytic welded on, they said $50. I show the next day and tell the guy with glasses that I called the day before, they said they would do it for $50, he laughed it off, haha, 50 bucks.Next he tries to say that the catalytic converter I had was not the right one, hes pointing at his phone, and Im like, but thats not the right car. He clicked on something and is like its still not the one.By now Im like, if you dont want to do it thats fine Ill go somewhere else.He responds,the only place that will probably do it is, Pepes muffler, in El Monte.

Stayed open late on a Saturday night to fix an emergency muffler accident we had on the freeway!! Great bunch of guys stayed to get it done. Spectacular job! Thank you so much! Without your help we could not of gotten the motorcoach down our driveway!

Great place for all muffler needs, been with them back when they were actuall on Valley and Nogalas!

Great service!

I had some much needed help and nothing but praise for this place. I am truly grateful they were that on a Sunday too.

Would NOT recommend this place to anyone. Took my car for brakes and rotors, charged me alot for 7 minutes. They left my brakes spongy with air. Promised theyd do a great job but I ended up taking car to another shop.First time I took my car in I asked how much it would cost. Then the dude was like let me take a look at it, then proceeded to do the work and then charged me without me giving him the okay. ... Not a good place for business!!! 0 stars

Owner not only fixed my car, he gave me sound advice on what to do to help resolve my problem. They are like family here. Repaired two of my vehicles on the same day. Great prices and service..... highly recommend Valley Muffler.

Mr. Dionisio is very nice and helpful. Been a loyal customer for a long time.

Good and proftinal

I love this spot, they always take care of my Camaro there. Hopefully be going back for more work.

Great work at a fair price. Fast and friendly.

I came here for a muffler delete for my 03 mustang, they did the whole process under 20 mins. They know what they are doing.

Hood price on a new muffler. Friendly helpful people

Ask for Tony if he his in. He hooked me up proper with a new ss flowmaster and installed it in 30 minutes and $40 bucks cheaper than another place in Walnut. Good guys.

Good deal and great service

Friendly people and bargain price for the repairs

THEY MOVED TO AZUSA ST NEAR HURLEY ST. hard working mexican bastards..i like them. ive been a costumer since 2005 ...recentlly they fixed up my gsxr 600 exhuast cuz i was running straight headers. cut right at the bottom, they managed to bend pipe really good cuz that angle was harder than heck trust the other valley muffler wanted 120$ (near vineland) same price but the dude down there refused the work at first. thanks valley muffler
