99+ GT aftermarket exhaust

[MattwantsSpeed]

Our next thing. which will be very soon, on my g/f's 00V6 Vert is dual exhaust. We've looked into GT-take off exhaust but feel an aftermarket exhaust system for a 99+ GT would net more HP gains? It seems to make more sense, right? And also adding an aftermarket H-pipe? Am I crazy or would this be better than a GT take off exhaust?

on a GT a cat-back is worth maybe 5hp.....so I wouldn't worry about that. A off-road H-pipe is a good idea and will add pretty good amount of power.
