Cat-back Question.
I'm not really sure what you mean by potential? Catbacks all make around the same hp (disregarding flowmaster). With that said I have a friend with borla, another with GMMG and I've heard corsa in person. The gmmg has my vote for the best tone hands down, corsa and magnaflow also sound really nice. I honestly dont care for the borla its very raspy even compared to the gmmg.

What I mean by potential is at the moment my car is stock. I have an idea of sound from friends and video of both as well as magna flow systems. I like the idea of the gmmg but I am also going to be doing headers. I am just looking for the performance aspects.

Just be aware that either of those systems will be insanely loud and raspy with headers. I had a GMMG and it took a lot of extra parts to tone it down after installing LT's. The system ended up weighing 1000 lbs. so I ditched it for a straight through 3" single exit Hooker Maxflow (like a Magnaflow).
A single exit straight-through muffler works well on a Z28 or Formula and is the best flowing system around (unless you go to duals). You can build it yourself using parts from Summit and it will be cheaper than any of the brand catbacks.
