Does anyone know why the exhaust tip is always black? I constantly clean what appears to be carbon off of it, but it always re-appears. What's up with that? My ride is a 2013 with 5000km on it.

It means your running rich which will happen on factory tune and is safe for your engine, the alternative is going lean with forced induction and the engine goes boom....

also if you have a new 2013 like myself there is a flash available to help lean things out a little bit and get better milage
i have not had mine done yet but it is a change to some emissions controls

but also like stated you want a forced induction motor to run rich rather than lean and burning holes in the pistons
the extra fuel helps quench those hot cylinders
