I got my used ESR pipe today. I put it on but the pipe is not even close to fitting completely over the BOSS billent flange. It barely reaches the 2nd oring and the pipe hits the frame. Should I run it like this or am I missing something?

Something isn't right with that pipe. It definitely shouldn't be rubbing against the frame like that. Is the billet exhaust flange bottoming out inside the exhaust pipe's flange, or is there still room to slide on if it weren't for the pipe hitting the frame?

That pipe could be off a smaller cc motor. Does it look like the same basic size as your old one? Maybe you didn't have a pipe to start with. I bought a pipe for a 250 once and it must of come off a kx100 or smaller kx, quickly sent it back in the mail.
Just something to consider, i am not familiar with the billet piece or the 250r.

It looks like some others have had the same issue. I do not have anther pipe to compare to.

ESR was very helpful...

If you want to run that pipe, it looks like a 1/4" - 3/8" thick aluminum spacer, 2 exhaust flange gaskets, and longer exhaust flange bolts would keep the pipe from vibrating against the frame.
Or, possibly grind away the welds on the exhaust pipe's spigot, move it out to the proper distance from the rest of the pipe, and then re-weld.

The last ones I got from Honda were metal, but they used to be paper, and I never had any issues with those, so yeah, paper should be fine.
It sounds like you're going to make a spacer, to move the billet exhaust flange out further from the cylinder. If so, don't forget to make a big hole in the middle of it.

Well, I can't use an angle grinder.
