I gotta say it... the best I'd heard so far was a stock exhaust that had been Stage 3'd, the baffling gutted.
I'm gonna gut one myself and try it... just for the sound of it, and see if it's what I want.
I have the V&H
2 into 1 Pro Pipe on both of mine, but the sound is only okay, but the power is great!
But, since one of my V&H systems is faulty, with a broken and rattling baffle... if they won't make it right, I'm going to experiment with a couple of other exhausts.
