Right sideexhaust....... normal,
Left side is rust color.

Is this normal?

 

Got any pic's of the pipe?

 

Both mine are still normal its an 05 with 7500mi & climbing

 

You mean the exterior of the pipe? I've got about 5k on my '06 Springer Classic and no discoloration.

 

No problems on mine (2006 Springer classic)4500 miles

 

I am referring to the inside of the pipe.
It was the same with the stock muffs as it is with the rinehart slip ons.
I just figure the left doesn't get as much exhaust flow and that is why
it gets the rusty color.
Just taken a guess.
Hoping to hear people say things like "Yep, mine too"
But it's not looking that way.

 

yep, mine did it too.... 05 Springer Classic 13,000 miles. .... until I replaced the gasket in the slip joint in the cross-over. Wasn't a loud leak but it pulled fresh air in during decel that made the outer edge of the muffler end cap brown. It's easy to change, pull the 2 bolts under the muffler & the 1 just above the passenger foot rest. The whole unit will slip off. Whenever I replace a gasket like these, I slather the inside & outside of it with Anti-sieze.
