woooo hoooo finally dropped the yfz at the Dirt Shak in St Joe to have some cam work done!! Just need to get my exhaust now and intake. Come on spring!!! Anyone have any suggestions on exhaust for the yfz450?

HMF makes a nice exhaust, and is reasonably priced, make sure to rejet

Depending on what kind of cam mod are you going to have done will reflect on what kind of exhaust will best suit your need's?

Dirt Shack does pretty good work, hope it does everything you want it to

Cam work done?.....Like your having the Cam mod done or something?

The pipe will depend on where you ride and what other mods are done to the bike.

If noise isnt a issue i would look for a Old school Nmotion pipe or a new JSR pipe.

Also dont forget when you get a pipe you will need to do some jetting on the carb same thing goes with the intake.

if i understand correctly, nmotion is now JSR? Or the guy that developed the original nmotion pipe is now working for JSR? I have looked online trying to find one of the nmotion pipes but noone seems to have one for sale JSR has also increased the cost, went from 499.95 for the full exhaust to $595!

just ordered my JSR exhaust and a Fuel Customs Intake. I cant wait to get this thing out this spring!!!

That is awesome.....Congradulations!

Thats awasome! Hope it warms up soon!

I have a Curtis Sparks and absolutely love it, all my buddies have Bill Ballace or FMF, Or others and I leave them all after 2 nd gear at the dunes, with the only difference being t he pipe
