REVIEWS

I absolutely love my Roadster Sport headers, mid pipe and Q muffler. I have owned a lot of cars over the years and the quality of your product is truly exceptional. The ability to tune the Super Q is very much appreciated.

Hey Brian, Recieved my Borla Dual Muffler Sport today from Fedex, and installed it in about 30-45 minutes. An Outstanding product with absolutely no drone throughout the power band, it sounds powerful, not at all like one of the ricey "fart tubes" that can be found elsewhere online. It has perfect like OEM fitment. Great prices, and great products. Product was shipped promptly and arrived as ordered. Would buy again!
