Stock LS1 vs. Stock 4.6L Mustang
My best guess is the WS6 is stock with manual transmission.
My friend's GT is bone stock with manual transmission.
The Mustang won by a nose.

SLP Loudmouth 1 vs Stock Exhaust LS1
My 99 z28 I had for two weeks. Bought it completely bone stock, put an SLP LM Exhaust on it.. sounded amazing. Highly recommend it, definitely picked up power too.
Only $400 is a steal too for a great flowing catback
Again this is a BONE stock car aside from the Exhaust.. No headers, no y-pipe, cats still there.
First part of vid is stock Exhaust for comparison
Trans Am Exhaust Flowmaster
99 Ls1 Trans Am, supposedly just a flowmaster muffler welded in to stock catback, but the Exhaust pipes were 3". So it may have been a full catback with stock tips. Only mods at the time were SLP lid and free ram air.
