I am selling my 1-week old B&B Triflow exhaust. The tips and cans have a custom bead-blasted, matte-black "stealth" finish. After installing the exhaust and driving the car 3 times, I am ready to go back to the Kelleners exhaust. The note is a low, rumbling, grunting tone...a deeper tone than the Kelleners but not nearly as loud. Asking price is $1250. Thanks.
