Someone stole the catalytic converter off my Toyota Prius. While they couldnt locate one for me they told me if I could find one they would install it for me. I bought a catalytic converter, a downstream oxygen sensor and a plate to reduce the possibility of it being stolen again. They fitted everything within 30 minutes and the charge was quite reasonable. I would definitely use them again. Im delgihted.

DO NOT USE THESE SCAM artists they qouted me a price I drove from boulder the doubled the price telling me I needed to cats when my van had one lol and they speak in Spanish to each other while laughing just dont use them they were another muffler shop on Colfax and they were closed not wounding why

Unbelievably fast and quality service. Dropped by as soon as they opened at 9:00 am with my Focus ST. Got a muffler delete, resonator delete and new exhaust tips for a good price and done in literally an hour. They centered the dual exhaust tips well and it ended up looking and sounding far better than I was expecting. car was ready and waiting when I got back!

Used to use them all the time for my tire needs. Wont go there again. Tire fell off before we even made it out of the drive.They didnt tighten the lug nuts, messed up the tire, the lug nuts. They put it back on and not even a day or to,was driving and the tire came off,it really messed it up. Fender got messed up, all kinds of things get messed up. Had to pay a wrecker to take it to our house. We fixed it but scared to drive it now.

They took care of me right away I recommend very highly to anyone to stop at the shop.I left very satisfied

Great service, fast, high quality, good pricing, Don Luis(wicho)and Don Chicha (Cesar)helped me out upgrading my muffler, very satisfied. Bye 👋

Very friendly and really helpful

These guys get it done. Had a alignment done and a downpipe put in my caddilac and the price was fair, these guys did it right the first time and i was out on the road again in 2 hours. I am going to bring my car back for exhaust work for sure

Great service at affordable prices.Truly professional and are willing to work with you.They will explain how its going to work out so that you have a clear understanding of their work.

Fast service. On task when you need there assistant very good price. And very humble people

HONEST AND REASONABLE PRICES,HELPFUL STAFF

I took my car for a tune up a month ago ($200). But now Im curious about Laze Es picture. There is a bolt missing on top of your radiator. My upper radiator hose just broke. I changed it. But I noticed both of those same bolts missing on the top of my radiator. Is that what these guys do?????? I was just about to take my car there because my car is overheating.

Theyre ok. If you can speak Spanish, they will understand better. Mediocre welds and they arent pretty but they get the job done

They are very reasonable with their price they got me in right away and took care off my vehicle they are very awesome

Good pricing! fast service! definitely going back for my maintenace needs

Although I have been a long time customer of this shop - I can now say with confidence that I will not be back. Do not visit this shop unless you like to donate money to have your car stored in their parking lot. They say they repair things that they really dont - and charge you for it anyway. Not to mention is takes them forever to pull your vehicle into the shop. This shop is run by crooked mechanics that prey on people and their misfortunes. Do not trust these guys with your vehicle. You are better off researching your problem and fixing it yourself. Also - if they cant read an engine code on their fancy Snap-On code reader they claim their is no problem - even though its obvious there is problem. DO NOT SUPPORT R&G MUFFLER.

Ive been going here for a while great prices and fast service! I would recommend to anyone

Very friendly and on the mark with what I had in mind, very far prices and nice work.Loads of options and accessories too.

Great customer service and affordable rates!Buen servicio! 👍

I have brought a couple of cars here for muffler work and have good work done here. Good prices and fast work when you come at the right time.

Talked to these guys on the phone arranged a price for some pArts and said I was on my way to pick them up.. And they closed early . I made it there 10 minutes prior to the scheduled closing time to find the chains up and doors locked

Quick service, price was about average for Denver. The welds are a little sloppy looking but solid and effective.

These guys are 👍 Great
