I recently purchased a Vortech V2-SQ for my 2001 GT. I currently have a mac catted prochamber and flowmaster american thunder exhaust setup. I read on corral.net that they gained 13rwhp by adding the magnaflow exhaust to their stock 99 GT. I had my car dynoed after installing both the h pipe and the catback, and I only gained about 3 rwhp. I haven't installed the supercharger yet, but the tuner that is installing it said I should change my exhaust setup. Do you guys think I should change the catback and the midpipe, or should I leave the setup I have right now? I am currently putting out 241 rwhp. I put in a new cam, which put me from 220 rwhp to 241.7 rwhp with the exhaust work. Thanks for the advice.
