Was wondering how much power I would pick up with the new exhaust I just ordered.
Got a flowtech x-terminator 3 inch orx with dynomax race magnum bullet mufflers dumped before the axle. Gonna have an exhaust shop bend it into place. I currently have an ory and flowmaster cat back. My car is cammed with longtubes as well.

Also....anything I should make sure I tell them or to watch out for during the install?

thanks

no ones posted, so might as well, idk exactly, but ive seen 20 HP gains with a corsa CB changed to a true duel system, you'll probably get the same if not more
