Might be abit early too see what exhaust works on this bike but thought id see if anyone has tried any aftermarket pipes at all? I know for dirt i more than likely wouldnt want any more power for this bike but mines set up as a full time snow bike and i want all the extra hp i can get.. I rode my buddies 2012 yz450f with yoshi on it back to back and this bike had so much better bottom to mid range snap and response thats mainly what im after is some better low end snap my fx has much slower roll on power till the mid range then really comes alive. I think the fx has a heavier flywheel which isnt helping the bottom end response thats another option i guess is swap flywheel out . I tried a different map this weekend that was supposed to wake motor up but didnt really notice much change. Hoping a good pipe will wake this thing up on bottom ?
