yuji if youre around perhaps you could advise me on the sound level increase from your free flow exhaust - my boat is currently booked in for a stage 1 kit and a straight thru exhaust - but i remember you just removed the resonator box and replaced it with a length of aluminium - how much sound increase was there - i am a little hesitant to go for a straight thru as they exit above the water line and are seriously noisy, i have been warned that a straight thru sounds like a c130 on take off and i am a little unhappy with that - so your help would be appreciated??? or any body else that has done this??????????

Hey Thumper if your worried about it you could consider a y-pipe shut off valve, I'm not sure how well they work on boats but it may be a possibility. Then if you don't like the straight thru you can run it normal.
