I've been fighting an intermittent exhaust rattle for about six months, and over the last month, I've noticed a gradual increase in backfiring. So, today, I'm on the way home from work, had to roll it on (bleep bleep cagers...) and a really nice blue flame shot out from under the seat. Nice black char mark on my pants. I was going to post here and ask what would cause it, then i found a beautiful rusted/rotted crack in the splitter off the rear head. Now that I know what caused the problem, can anyone tell me: What would cause the problem/rusting How much of a pain is it going to be to back the exhaust bolts out, given that they are prob rusted too If anyone has a header pipe they would be willing to sell for a reasonable price, because they have it laying around after replacing thiers with some fancy aftermarket piece. Much obliged. Pic attached.
