426 exhaust options

Will an exhaust system from an 03-05 yz450 fit on an 02 426? They look like they have the same mounting points, just not sure if there's any difference in header diameter or any other issues.

No they are different... Not much exhaust pipes fit the 426s. I know FMF makes a couple and pro circuit

Weird. I actually have a stock muffler from an 05 on there now. It fits fine no mods needed. Doesn't sound too bad either.

Hard to tell from this pic but you can see the "cone" tip on the muffler

"Some" 450 pipes will fit, some won't, some will with a little work.
