best exhaust system for 2001 yz 426

i'm interested to know if anybody has changed the stock system and gained considerable performance. please pass on your suggestions/experiences.



Just keep your stock exhaust and take that $400+ and put it towards the suspension. You will be MUCH happier, and MUCH faster than you would be changing the exhaust.

But if you do decide to get a new exhaust, I'll buy the '01 stock header from you. E-mail me if you are interested.

I have done my suspension and put a pro-meg aluminum without and disks in place and have been very happy with the throttle response. The only jetting changes were to raise the clip one on the needle. Good luck.
