borla, IMO, sounds like total ****, even with stock manifolds. with LT's, it sounds even worse. rasp, popping, garbling, you name it. YUCK. the only thing worse than the sound are the tips. ugly.
gmmg is far superior in all areas. that being said, if you don't have cats, gmmg rasps also albeit not as badly as borla. however, you have an LT1 so it most likely won't be that bad. that big old iron block may not be as fast as an LS1 but it sure sounds a lot tougher than our all-aluminum screamer motor
IMO, you'd be a fool to get borla over gmmg for any reason, ever.

gmmg is IMO THE best sounding catback. i love mine. i had a lot of rasp though when i took the cats off but all you have to do is buy a dynomax bullet muffler to weld in the intermediate pipe for $40 from summit and the rasp is gone.
