Honda CRF 450 L question

[Sefu]

Hi lads, Im picking up a CRF 450 L tomorrow that has a Honda OEM Powerup ECU.. Air intake etc

I'm curious if I can put an aftermarket exhaust with that powerup kit?
Nothing online says that i cant but thought id ask?


Also curious who else here has a CRF 450 L and has any tips to share?
