After riding with the F1r for a little bit I noticed an exhaust stain at the bottom of the exhaust where the rivets attach the pipe. I put my hand near that spot and could feel air leaking just like the stock pipe's drain hole. Is this a big problem? Any suggestions.
they mention using a high temp silicone on the rivets in this repacking how to.
