CORRECTION on that picking up some hp.. I have dyno numbers to show your TSP bullets killed my HP and RWTQ. Nothing changed on the car but the exhaust. I also noticed when I picked it up from the shop it fest like I lost some tq as well. also with my experience with tsp, ill never purchase anything from them again. EVER
