If its still to load, rock the stock pipe. I use the stocker with all stage III's, no problem, the bike still rips, no melted plastic, no burt leg, and no cops called!!

Yea in the day this was the best way to tune an exhaust rather than fuck'n with the carburetor jets. To decrese the back pressure,(lean your motor out) you would add rings. To increase the back pressure, (richen up the fuel to air mix) you would take disc out.
![]() They have a patent on this method I believe because I have never seen any exhaust use this method and it's easy as hell to adjust. ![]() On a stock CRF 50 exhaust there are 3 allen bolts in the back of the pipe. To tune the stock exhaust you get a few small washers and stick them between the spark arrester and the pipe thus decreasing your back pressure.

ok well i just ordered a complete mint stock exhaust off ebay yesterday for 60 dollars. I re-packed my fmf and it got louder. did'nt go with the oil filter mesh idea because I wasn't sure how that would affect performance/etc....
