2003 YZ450F exhaust?

6 posts in this topic

What years are compatable with the '03 exhaust? I destroyed the White Bros muffler(along with the rear fender and sub frame) that was on the bike.

Thanks,

Mike

Will taking the "stuff" out of the end of the WR muffler make any difference? I'm hoping that the White Bros. muffler is salvagable, if not WR muffler maybe a temporary fix.

It wont make a huge diff, but you may notice a bit more power. Keep in mind that if you pull the spark arrestor you will no longer be legal for anything but the tracks.
