Looks like a pretty dead thread but its sticky'd so why not...been watching just about every sound clip I can find and am no closer to deciding on which exhaust to buy. The 3 choices I've narrowed it down to are as follows. I've never seen another modified Z around my area so it's hard to get a good reading as to how these exhausts compare. I am coming from a catless HKS true dual on a z33 I just sold and loved that sound...deep but loud with lots of backfires if that helps you help me at all
1-Motordyne shockwave
2-HKS Hi-Power
3-Greddy evolution GT
