hey guys, im considering a atc 250r powered cr 500 motor conversion. most likely an 80's model 500 motor (85 and up), and i was wondering how bad it would be to modify a pipe for it....ill upload pics of the build

The cut and twist method is the easiest way unless you want to start from scratch.

[william16339]

should i start with a fatty or PC pipe?

Read up on those exhaust and see what power they put out and how they change the power.. Everyone likes there own exhaust.

i see,thanks..with all the botomend,,i want a pipe for topend or mid range..a cr 500 i think has enough bottom lol

[lazybiker79]

There a little hard to control if you want all top end. But thats the fun of it...

[william16339]

yup! what did you have?
