Sweet Thunders
What are you asking about for volume? In the cabin? outside the car? You running cats? Any setup with a cam, LT headers, x pipe, no cats, and race muffs will be, generally speaking very loud.
From what Ive heard, dumping at the axles will make it louder in the car.
I have no exhaust experience with LS1 cars, but do have some with other platforms. I would ALWAYS run a hi-flow cat. Keeps the car clean, smells better, and keeps the sound more crisp and deep.
I bought the sweet thunders for my 6.0, they lived up to their name. I got rid of the added glasspacks, and couldn't be happier with them. Adequate rumble at idle to live up to the "sidepipe look". Highway running gives a nice sound, as opposed to the respy growl the OEMs had. These are sidepipes on a vette, exhaust exits about 3' below my left ear. Rear exhaust shouldn't be a problem.
Quality was very good too.
