Hi magnus, welcome to the site. You need a 2.5" or better..3" on the intake to miniminize restriction. The CVT can be 2" but not the airbox intake. Top it with a 180 turned back. MIMB has some How Tos on it.

Thanks! Ill try 3 in. I ride in mud and water so much I need my snorks at the chest level.

Welcome to the site. I'm no mudder but chest level snorks sounds like you go pretty deep!
