If you are ever going to go with longtube headers and an off-road Y - you'll regret buying the GMMG! Other than that - can't beat it!

Yea, if you plan on ever getting headers and a catless y pipe, just get true duals now. With any catback you'll need to keep your cats to avoid rasp out the a$$.

Does anyone have any sound clips/videos of the gmmg exhaust on their ride? Preferrably close to stock as possible?? Would like to hear what this exhaust sounds like without all the mods. Thanks in advance!!!!!

No regrets here either... Sweet lookin' and soundin' exhaust system.

I think my setup sounds pretty good

yeah it does and i'm really wanting to hear a clip of you driving in it...cars sound so much different when revving than actually driving...i hope mine sounds like that...i've heard a couple and they are pretty raspy but yours seems to be different...are your pacestters the new improved ones?

I am going with the Kooks LT headers to catted Y - to GMMG exhaust. I already have the headers and Y, now if I can only find a good deal on the GMMG.

I missed out on the GP by two weeks

I waited 2 weeks too long to get my ls1 fbody

I say get the GMMG cat back. It is praised by most everyone on this site. I deeply regret getting Flowmaster, it sucks and sounds worse than the GMMG. It will be a good $700 spent if you get it.
