Default Re: OP Cruiser, first build

Yeah, could be.

I understand expansion pipes, they do work well. They are also loud but at least you get some performance for your pain.

This thing is a muffler and it works pretty good. I blew though it and it is restrictive, I could feel the pressure. That same pressure is what keeps the charge in the chamber I think, because the low speed torque fell way off as well as the high speed 4 stroking issue.
The only thing in my garage with 4 wheels is the lawnmower
