Was very ify I getting this . But 2001 HONDA 400EX FIT ON LIKE A GLOVE... Very happy and order came in within a week. Came a whole day early on first date given. Coolingsky??????????Great!Part arrived quickly looks good and fits very well on honda 400exPipe looks good on the bike but there's some thangs about it Like the stock one on the end is the same so I had to crimp my FMF on their a lot. When it heats up it will change colors If you go through the picture list you'll see more of measurements. But I love it for now!
