Best Sounding Catback
Magnaflow, relatively quiet deep sound while cruising but sounds like a NASCAR once you get on it. 396 with LT4 top end, CC306 and FLP long tubes with off road pipes. Once you put the cats on, it quiets down considerably.

LT1 = Iron block
LS1 = Aluminum block
They have different firing orders(I don't know the exact orders off the top of my head, but search if you like)
The LT1 and LS1 do not have identical camshafts or heads(obviously) so that will definitely change how the already outlined differences are affected.
A fair share of LS1s came from the factory with an SLP exhaust(SS)
And I'm not positive but I'm willing to bet they don't have the same sized valves.

It's funny how subjective exhaust sounds are. I don't think the Borla and GMMG sound anything alike on an LS1. The GMMG sounds 10,000,000 times better IMHO!

Both of the videos above are on my 97Z-28 (pacesetter longtubes, and ory)
My vote is for the corsa. i really like how it sounds. real quiet at idle and starts to open up when u get on it, and the tips look amazing!! the loudmouth was just plain loud, from idle all the way to redline. i found myself being threatened by my neighborhood police officers all the time after the headers and ory. i do love the sound of the borla though. and the gmmg i think is loud but it sounds good doing it. now what im going to buy, is a cutout/with electric motor for when i want to be obnoxious and when i want to have a conversation its quiet at the flip of a switch.
