My car runs so good after bringing it here! Thank you so much, I have taken my car to other places and never had it checked it as thoroughly. Extremely nice, honest, fast, and thorough repair shop. This is definitely my go-to shop for maintenance and repairs from here on out.

Stephanie

He'll treat your car as if it was one of his own. I honestly can't say enough good about my experience with Sonny and his shop. Forget everyone else, bring your Rod, custom, classic, specialty car or everyday auto/truck here for his services - you won't regret it. Dollar for service, I doubt there's much true competition in the whole of SoCal. Awesome.

Adam

I came to the shop to have my Mercury Grand Marquis converted to dual exhaust. Matt put together an awesome Magnaflow system, H pipe, and chrome tips. Sonny did the work and you would have thought he was working on a Rolls Royce with the care and precision he was putting into my car. The H pipe he made was perfect. Everything looks absolutely perfect and it sounds great! I highly recommend Sonny's Muffler shop and will never go anywhere else.

Steve

I wanted to say thank you so much! The exhaust you put on is perfect! There open on Saturdays so you can't beat that for all you marines/sailers out there that might work all day.

Luke

I had an old truck that needed exhaust work. Sonny's did a great job in a reasonable amount of time for a great price! I can't say enough about the quality of the work that they did! I highly recommend them.

Vern

Sonny and Matt have done great work on 3 of my vehicles and I plan on continuing taking my business to these guys. Very honest, reasonable prices and quick turnaround on the vehicles. Definitely recommend.

David

Sonny and Matt are the best. They have worked on many of my vehicles and have always done perfect work with resonable prices. I had them install an H-pipe on my 2018 Mustang GT, it sounds sooo good.
