Had these guys install some borla mufflers onto my GS. They installed the mufflers, fixed a problem the previous shop caused, and lined everything up perfectly. They work on some higher end projects as well. Great shop. Great prices too.

Just picked up my car, everything is smooth clean. Great craftsmanship. Matt knows his stuff, he will guide you towards choosing safe reliable components. I went in with completely stock 2013 Camaro ZL1. 3 days later he gives me back a 720 rwhp monster. Thank you guys.

I had a bad fuel injector, Matt told me to bring it in on Monday. Wednesday he told me it was ready. The car runs like a "bat outa hell", his techs did the work for a third of what the dealer said.
