Right now I have bbk shorties into an offroad h-pipe (2.5 inch i believe) and then stock pipes with flows. I'm thinking the stock pipes may be hurting my performance a little with a 347, but I don't have the money to spend on a full catback right now, so should I get dumps or will it really effect my performance or not? main thing I'm wondering is performance gains on this cause I have driven a car with dumps and it was loud as hell so I'm not sure if I want them or not yet.</p></blockquote><p></p>
