exhaust setup

I think I've heard about every combination there is, and in my personal opinion, if you're leaving the headers and cat alone, go with the SLP Loudmouth with dual/duals. BUT, before it's put on, have them weld a stainless deflector in the pipe at the split into the dual set-up. Essentially, the pipe goes straight back after the cat, then after the axle, y's into two pipes; the deflector pushes more air to the far pipe, and helps to balance the rasp out in higher rpm.

Otherwise, I'd STRONGLY suggest the following: True duals ran through Magnaflow mufflers, Dr. Gas X-pipe, and QTP longtube headers...bolted to an LS1. Sorry, but after a few attempts in the ol' 6, this is the only thing that satisfied me!

Iv got Flow master 40 on my 4.3. It sounds good under 2k but anything higher than 4k it is really blurry
