Tip for slightly quieter exhaust

[Gustav]

Only made a small differnce,just kinda took the shrillness/high frequency down a bit,it was on a loud pipe.i don't think there'll be a way to solve the high noise levels,they need the pipe to resonate as i understand.I don't have any neighbours for a good 1/2 mile or so,so i used to keep the nitro for the crappy weather, but i gave up on nitro stuff in the end when it annoyed me for the last time.
