Jettin with new pipe

[bcg717]

I have a 06 400ex with a k&n filter. I'm getting ready to buy the hmf sport series slip on. Should i (do i have to) buy the jet kit that comes with it. I live in georgia and i will be riding mostly tracks. Also should i get the spark arrestor and quiet core. Thanks for the help

You don't need to buy a $50 jet kit.
Just call HMF, or go to their website and get their reccomended jetting and pay $8 for the required jets. ;)

I would do the same as recommended by bwamos

agreed^^^^ if u r strictly track riding then u shouldn't need the quiet core/spark arrestor. but be warned......THOSE PIPES R LOUD!!!!!
