Martin back with a new project and a hit list for us to tackle! We first thermo-coated his headers and Y pipe, then high temp wrapped everything up. Then we built a custom SS back half system that included a muffler for both date nights, and getting rowdy with his troops. Dual tips finished the look he was after and we love the end result. This car rips!! From Corrado’s, to MR2’s, and now an LS swapped BRZ … Thank you for roughly 15yrs of loyalty and repeat business Martin! 🍻

Tony’s 1989 Range Rover is getting more attention in all the right areas. Custom cut flanges, custom collectors, and full SS test pipes complete round one of his plans for this awesome time capsule. Thank you Tony for being such an awesome dude, and thank you for the beginning of a great business relationship!

Nice exhaust system installed for Ahmad .
Love the fit and finish of this system on his Audi RS5. We love being your local dealer for these proven systems!

Steve’s Ford Pinto in for some additional chassis bracing and plans for a future exhaust upgrade. I installed this rollbar and upper strut bar for Steve roughly 22 years ago. My brother painted this car when he was 19, around the same time. Steve built everything else himself. The whole car still looks amazing to this day.
