Post your sound bytes here.
I don't have any actual sound clips, but I can contribute a few videos with decent sound. I'll have new videos soon, so I'll add them as I make them.
In the mean time, this is my 318 Dakota w/ stock manifolds, a stock y-pipe, 2.5-to-3" mid pipe, 3" DynoMax Ultra-Flo cat-back system (canister style mufflers), and a 3" MagnaFlow Powercat:
This is my '72 Demon 340 w/ TTI 1-5/8" step headers, 8" collector reducer, 2-1/2" tubes to the bumper (no x or h pipe), and Flowmaster Super 40 mufflers.
