86 250r exhaust setup

[KY250r]

i just did a short rod to long rod converison on a 86 250r. im looking for a good exhaust system for it and jetting. what pipe and silencer will wake it up quite a bit? i mainly do mx and trail riding, and also a bit of jumping.

Might try it in the 250R forum. Probably get a few more hits and everybody in there has one.
