It sounds really good, it flows really well. It's also expensive as HELL for a catback, and in my opinion WAY overpriced.

Look around on ls1sounds.com for some LT1 clips with the GMMG, that'll give you a clue as to what it would sound like on your car.

GMMG get their tubes from StainlessWorks.

Summit Sells Stainless works tube mufflers for $129 each.. buy 2.. have a shope bend up some pipes for you.. its better than spending $700+ for it..

i'm right now looking at buying 2 of the 3" to 3" chambered mufflers from summit since i'm designing my own dual 3" setup. i'm also wondering how well they sound, i want my car VERY LOUD but yet to sound good, and i wanna know how well they perform? say a mild 383, 11:1 comp, sittin a little over 400 hp? also, what does everyone think about making my own "X-pipe" or crossover pipe... i'm wondering how well they benefit performance and sound and if its worth it for me to bother creating one... thanks!
