I am still having issues deciding which mid-pipe I want (I really want a Magnaflow catted X, but there are other things I want to do on the car while I have money). Because the price of the o/r MAC h-pipe, I am leaning to it. Anyways, is it really worth upgrading to a aftermarket o/r H-pipe, such as MAC? Or would it not really do much? What type of gains could I see on my 02 GT?

Thanks for the help!

Do you have any other mods? If you're keeping the stock mufflers, the H will sound better than the X, IMO, of course! You will gain HP with the O/R H, but it will be higher in the RPM range, so it might FEEL like it loses a little on the bottom end.
 
Get a VRS O/R X...its a true X design and sounds AWSOME, just like my Dr gAs. Most people who hate Xs heard non true X designs...they sound BAD. True Xs flow better than Hs and give more power...The magnflow is also a true X design, but im not too sure about their price vs the VRS. Dr gas needs to be welded, so im sure you dont want to do that.
 
The O/R H sounds great in my opinion.. I have 40 series flows on mine along with it. I got the "coated" version for an extra 15 or 20 bucks from Brenspeed.com.. pretty easy install, and haven't had any issues with it.

Gainwise, I actually felt like I lost a little torque at the bottom end, but it probably is made up for up top.. I think somebody posted a dyno sheet a while back where it shows that the torque basically just moves up in the RPM range .. it doesn't vanish, just moves.
 
I also have the MAC Prochamber and flows on my 01 GT and it sounds great! The car has a head turning rumble. Mine also hase long tube headers so this really makes it rumble! I have heard the MAC Prochamber on 2 other GT's (02, 03) and they sound great as well and they don't have headers!

MAC Prochamber would be my vote!:D
