[Carcher]

Not expensive please, What's a OK pipe for my 66cc. I've extended it already about 12" the factory muffler.

everything about the motor is still unchanged? will you upgrade these things as you go?
many questions when choosing a pipe. you can open up the factory muffler and take out the baffles, leave cap off for free,, but it is LOUD

what do you want to do with your bike, how do you want to ride it?
