bisson muffler os 1.60 apc 18x6w
Has anyone noticed how small the exit holes are for the bisson pitts muffler for the os 1.6? Has anyone cut the tubes and not had major backpressure problems? I am running my tank near the firewall and think I have plenty of backpressure to cut the tubes. I have been told I can get better throttle responce and more power by releiving more exhaust.
