Exhuast system for a yz400f

I need a cheap pipe for my bike. Anyone know where and what to buy. And also if anyone knows if a jet kit in my Yz400f would stop the caughing it does.

Do you want aftermarket or stock. I have a extra stock pipe.

Check out this site motorworldracing . Scroll down to YZ400 jetting. I have a big gun pipe and love it. I ride at 2000 ft and have my jetting one size leaner (178 main, 50 pilot) than is listed in the guide. It works great. :)
