Vciferni you werent at corsons yesterday were you? your ski looks familiar, and id say the best exhaust mod is relocating the box to under the right food well where then you can rout either to stock outlet or plug the stock and go right through the transom. there is a really good thread for if you search like 760 waterbox mod or something i cant find it but maybe someone else has it saved. it gets sooo much of the sound behind you when you ride, its really nice.
