It's the cheapest, and it sounds the best. On those two points most people agree (with the exception of the GMMG people [those do sound pretty pimp]).
If you were to take the worst / suckiest aftermarket muffler, and stage it next to the almighty GMMG, you would probably see a dyno difference of less than 5hp. That's so insignificant a number when you're talking about listening to the car every day, and spending another couple hundred bucks for one of the 'better' units.
That's the way I see it. Again, I would ask anybody who thinks differently to please point me in the right direction to find the proof.

I have one+elec cutout--lotsa people say mine sounds great-I even have cats and stock manifolds--!!!!
As for the "Flowmaster sucks" debate, all I've got is personal opinion and experience. My car came off the used lot with a Flowmaster, SLP y-pipe, and stock headers. At the dyno, I made 302rwhp. Then, with a cutout after the y-pipe, I made 322. But, like I've always said when people choose inferior parts - I just hope that I run against YOU when I go to the track!
1) its all stainless
2) i got a good price on it
3) Its the best sounding exhaust, hands down, IMO, and many others
4) it just happens to flow the best
I had flowmaster before it, and they arent even comparable in sound. Flowmaster sounds decent at idle, gmmg just sits there and "burbles"
Flowmaster wasnt very loud at all on accel, until about 3500-4000rpm, gmmg just barks over 2500. Up top the flowmaster sounded pretty good, but nothing like my gmmg. I have always said buy exhaust on the sound, flow is nothing more than a $30 cutout away.
Here's what the IROC ran with the 3" Flowmaster catback: 12.39 @ 109.5. Then NOTHING else done except a 3" cutout put in the y-pipe and opened up: 12.17 @ 111.93 MPH. That's a solid 25 HP gain. I've seen people only gain 5-10 rwhp with cutouts vs the Hooker and similar flowing exhausts.
If you want loud and nasty, get a straight through (bullet style) muffler on a y-pipe
If you want louder than stock, but more refined get any of the 'normal' style catbacks
If you want it to be loud and still sound fairly pleasant, get bullet true duals
If you want it to be deep, mellow, smooth and just plain sweet, get real muffler duals out the back.
If you really care about HP, forget about a catback and get duals.
