When I swapped out to the new fuelmoto headpipe, the old gasket kinda bonded between the old headpipe and crossover.

I opened up the old clamp to the max, took a large tapered socket and opened up the crossover a bit, boom, new gasket everything went together like duckbutter.

When I pit my new head pipe on I rented the pipe expander. I loosened the clamp as much as possible and left it on the pipe as I used the pipe expander, worked without a problem.

What are you guys talking about ? I don't recall any gasket being used on the crossover pipe. Anyone have a pic or part number ?

I replaced my gasket twice, after that I replaced the entire head pipe with this, no crossover.

Gasket Clamp 66813-09. There definitely is one. I have been driving around without the gasket and there is a hell of an exhaust leak going on. Had to order additional gaskets. Dealers don't even stock them. Dealers seem to stock very few parts for our bikes.

I believe FM addresses this issue on the header install sheet. Crossover must be installed at a right angle and twisted into position to avoid damaging the gasket. At least that was the case on my 16’ RGS

Get the exhaust pipe expander; less than $10. The crossover does not need to be expanded too much and the clamp WILL fit. Slide the expander in about 1 inch. Took me twice to get it open enough, for the gasket to go in without distorting it. I used some channel locks to open the clamp enough to slide on. My gasket is protruding about 1/8". Install the crossover and the crossover hanger without the slip-on. Get all that tightened up then install the slip-on. I did have to use a hammer handle between the swingarm and crossover (near the outlet) to push the crossover down to be able to slide on the slip-on. I also used the expander on the slip-on to make that easier. Don't forget a little anti-seize, before installing the slip-on.

Don't feed the MOCO unnecessary money. You can do this!!

OP... this is the ticket... it's really not that hard if you take your time and use the right tools...

I installed a headpipe on my old bike, and a friend's, this was the method I used... it really wasn't an issue at all. O n mine I changed the gasket, on my frined's bike there was no need to replace the gasket...

As mentioned, I also expand both mufflers before putting them on... and always use anti-seize... remember, you don't have to split them wide open, just enough to slip over the pipe (or fit the gasket)...
