Need Help

[DELOS02GT]

I know this has been beat to death but I need to know some info about exhaust for my Mach. I heard that you get the most gain from the mid-pipe, but I was told the other day that the cat-back gives you the most. I was going to do MRT H and weld in some flows to the stock cat-back, but now I'm not sure if I should buy a cat-back and leave the stock H in. Also, what sounds the best on the Mach? I heard Magnaflows, Catted X and cat-back, but it was really deep and quiet. I like the hollow sound of the flowmaster but their stuff isn't stainless, and I want to spend money on stuff that will last a long time.

I'm not a Mach 1 but I noticed no SOTP increase from my catback on my GT. The mid pipe was -very- noticable. Gained 2 MPH at the track with the mid pipe, the catback did nothing.

Mid-pipe will give the most gain. Catback is worth maybe 1-2 hp and is more just for sound......

I still need to get one. I'm rolling with the stock mid-pipe right now....
