Najar’s Muffler Shop And Auto Repair 1454 Rumrill Boulevard, San Pablo, CA 94806

"Best shop around, had a new cat-back exhaust installed and a catalytic converter job done here, don't bother going anywhere else"

"I’ve had bad very luck with auto/ exhaust shops in the bay (I’m feminine if it matters). Najar’s did an AMAZING job, had photos of what they fixed, and charged me WELL below what other shops bill to even look at a vehicle, much less fix it. The shop’s a bit out of the way for me, but I would fully return & recommend friends. We’ll worth the drive, 10/10, for service, quality of work, and rates."

"Affordable prices for catalytic converter repairs. Had one catalytic converter replaced due to not passing smog check. It was done within a day. Afterwards my car passed the smog check with flying colors."

"My catalytic converter was stolen, sawed off completely with my CO2 sensors cut as well. I called several muffler shops to get an estimate. Cheng Auto gave me the lowest price over the phone. They had the parts ready and they did the repair within a few hours of me dropping the car off. No surprises, just great service. Skip Midas or other big chain garages and support these local guys. Job well done!"

"My jaw dropped when I was told the price however, they did a really good job. And when I pulled in they were prompt at the time of my appointment. The men were very kind and fair. In and out in 26 minutes. I felt that $189.95 was way to much for labour for only twenty-six minutes. However, I was satisfied when I left. Thanks Cheng Auto Inc."
