Need some help here. I have a 21' Schiada V-Drive with a Chevy 502, set up with twin Gentry Turbo System. Currently, I have stanless pipes coming out the turbos. The boat is set up for ski racing, so no through haul exhaust. At idle, I'm coming in at 89 dB. For Idaho and Washington, I stand out like a soar thumb and the lake patrol is on me. I carry around a pink slip that notes 89 dB as proof that I'm legal. I figure if I add mufflers, they'll leave me alone - so I won't have to use the run and hide approach. When I even touch the gas, the 89 dB is shot to hell. Any recommendation on mufflers? Also, anyone have experience with the custom pipe setup, since I'll need to contact someone to get this layed up. Thanks for any suggestions.
