I was wondering for my 250ex what kind of exhaust would be better and i was thinking about the yoshimura or white brothers and a bunch of the other ones but im not sure which one might be the best for the machine?Also i was debating on the maxxis razr or the maxxis razr 2 for my kind of riding?

 

A good friend of mine just put a Pro Circuit T4 on his 250 and he really loves it. And it's not that expensive (200 bones)! Any one of those two tires are great!

 

the white bros e-series works very well on the 250 ex without being overly loud ,just be sure to re-jet appropriately.
