Going back to stock exhaust questions

[badjoka]

I currently have the Riva rear exhaust and miss my days with the TJ (RIP) exhaust mod. The rear exhaust really cleans up the hull and has an amazing sounds at idle, but also (IMHO) an annoying buzz at any throttle position after that. Guess I'm getting too old.

Finally have some free time to finish up the ski and want to go back to a quiet exhaust.

I'm not exactly sure what makes the stock exhaust so quiet. Is it the #1 resonator, the #3 water tank, or #2 the rubber bend, or the combination?

I really don't like feel like reopening the old stock outlet (used #5200 to seal it, remove pump, ets.,) and sealing the rear exhaust hole, maybe I can add the water tank and resonator to a modified rear exhaust to get it back to quiet? TIA!
