Interesting about shortening the exhaust and pointing it to the ground with a decrease in the 2K drone.

From experience on 2-stroke dirt bikes many years ago with after market noisier exhaust we were able to take a lot of the bark out by cutting a 4" piece of motorcycle tire tubing and sliding it over the end of the muffler 2". This left 2" of tube sticking out in the air. Big difference in less noise.

I wish that I had hose clamped a 4" to 8" piece of old radiator hose on the end of the exhaust before converting from the Gibson muffler to oem and drove for a few miles for any difference in sound.
