I searched and couldn't find one so I decided to start one. With this engine being able to produce so many unique sounds, I think we should have a place where some of us can post up what ours sound like. Also, this should be able to help others when they want to find out what setup they'd like to run.
I'll go first.
Mods to exhaust system:
"Suitcase" (first muffler) and resonator delete. Cost:$75
