Try a Venom Shift Kit to lower the rpm’s, thus quieting the machine. JD Clutch Doc is a dealer. Contact info@jdclutchdoc.com for more information on the Venom Shift Kit.

I just replaced my exhaust pipe, this part AM146297. Exhaust actually comes out of the muffler now!!!!
Before my 2013 had leaks at both joints. The manifold side I believe was wrong angle of curve from the factory.

I too am wondering about an additional muffler such as the Silent Rider. Have you read about them?
This is a muffler that attaches to the factory muffler.

One more comment, I am back on this forum after not posting for a couple years. I came back to search for a way to reduce RPM so I will be looking at the Venom weight kit that Brad Hill mentioned. Several older posts speak about installing the 855D clutch. I need to read and ask questions before I do anything.
Good luck!
