2002 Pontiac Trans Am WS6 M6 - Stock/Borla Exhaust Comparison
Exhaust comparison between stock and the Borla adjustable catback with the 1/4 plate, mainly to give people ideas of what brand of Exhaust they want, and how much better it sounds/looks over stock. The completely closed plate is very quiet, and the 3/4 & wide open plate is loud and can backfire a lot. I think the 1/4 plate is perfect. Only other mods are SLP lid, UMI short stick, and Corsa clone Exhaust tips.
