Tri-Valley Muffler & Brake 6447 Golden Gate Drive, Dublin, CA 94568

"This review came late but this place is amazing and when I got my catalytic converter stolen they were the only one that had one for a reasonable price and they got it put in place super fast! They held on to their last catalytic converter just for me. I can’t recommend them enough!"

"Outstanding business, pulled up with a muffler problem in my 03 Mini. Owner looked at it, pulled the truck down from the lift he was working on. Pulled mine up on the lift, fixed the muffler issue in about 10 mins. Outstanding service! Highly recommended this business! Wish there was more businesses like this in the Livermore/ Dublin area."

"Came on a Friday short noticed, had a direct bolt on aftermarket part needed to get installed and owner didn’t hesitate to take my brand new car on lift and begin working. Appreciate the fair cost and very quick turn around time. If I’m ever in need of additional service I’ll be back."

"Needed a resonator delete and install an xpipe on a B9 SQ5, same day in/out. Most places in the area including Livermore had 2-5 day wait. Pulled up, 30 minutes later I was on my way. Great service and quality of work. Gonna come into to get rotors, brake line and pads installed soon!"

"This Corolla sounded like a street bike with straight pipe. It's back to smooth and quiet like a ninja within 10mins of arriving at the shop."
