No Peashooter? 07wr450

Recommended Posts

Is it ok to run the stock tail pipe with the whole insert removed? I've got the gytr muffler insert on order. Been riding with just the cone/spark with no insert at all.

That's the way I run it (AFTER rejetting and opening up the airbox).

Bike was tested at 95.7db today with no insert at all and all free mods.

And I believe that's legal for California :applause:

Yep

My 2005 stock (except for jetting and throttle stop) WR450 with the exhaust insert replaced by a PMB insert tested 93 dB by the ranger.
