cfm airbox

Are they good airboxes?
And will i have any trouble puttin one in if i have a 400ex shock?
Also i would have to modify the rear plastics by cutting out the airbox on it wouldnt i?

yes, they are good boxes i like mine. i cant say about the 400ex shock because i dont have one. yes you will have to cut out your old airbox i just used a air saw and it worked great.

I run one and love it.
I can't remember where the rezzy is at on the 400ex shock but
if it's the same as a YFZ450 rear then yes it will fit perfect.
Maybe this pic will help.

thanks that helps a lot.
wont hit the pipe though since the rezzie is on the right?

Nope your good on the pipe.
Lot's of guys run the YFZ450 rear without pipe issues.
Maybe one of them will chime in for ya.

heres a pic of my 450r shock, and it rubs my airbox and i had to heat my snorkel and bend it up to clear the rezzie, i think this rezzie is a little larger than the 400 ex one so the ex might work, but the ex is positioned the same not off to one side, but as you see it's tight in there, im thinkin that that carb tube on paulie's is gonna interfere
with the rezzie????
