    Ideas Needed For A New Exhaust Set Up For Bumble Bee

    Guys i have to quieten the ski down as the water police and the local race club has to stick to there rules i know its suck because right now its sounds CRAZY.

    We need the best power as posible and try to get it allot quiter since i had the mis hap this weekend might as well start now on a new system.

    I currently have 2 gibson on a dual exhaust set up pictures attached. But would it be quieter with a TDR water box i don t think it will

    My idea is still using the 2 gibson i thought cutting the ends of the 2 gibson and making one long one and 1 outlet only and blocking one off.

    Any feed back and ideas will be great here.

    Mike

    Try to inject water into the exhaust to quiet it down.

    Mike, don't worry with a TDR water box... use what you have... maybe just put the two Gibsons in line rather then parallel?

    You are going to need sound suppresion in some shape or form...I am dumping water into the exhaust outlet from the bottom of the J-Pipe and it is still loud.

    FYI - the black sound suppresion box from the GPR is the same as in a FX HO and very similar to the one in a SHO. I plan to use the GPR box once my set up is 100% proven.

    Another thing I will try is at the exhaust tip of a FXHO and SHO they have what they call a valve it looks like nothing more than a cover. I dont know why they put it there but it must do something for the sound.

    Bruce used these in his SHO build.

    The 1st plan off attact will be

    Whats your thoughts on this guys

    Same pipe that s coming of the header extendend or new one runing one Gibson only like an RXP set up but feed water in front of the Gibson and 2 x water injestion right at the rear off the exhasut tip to muffly the noise.
