Default Re: how to make an engine quieter/stealth

Wow you guys think the SBP expansion chamber makes the bike quieter, heh my experience would be it is 20% louder .....15 with the "silencer" on.
I should test it out but i found a 1/8 scale rc car silicon, exhaust outlet made more of a difference than the "silencer".
Maybe if i am feeling better tomorrow I will dig out the DB meter and see what is what.
