Hot Head Pipe

[Massimo]

I just put a Two Brothers Muffer and cat eliminator on my 96 r1100r.
I'm noticing that the head pipes are turning more blue then they where.
I just started riding this bike so i don't know if my pipe is running hotter exhuast do to the muffer change
(less back presure) or if it's just normal. I have no other mods or upgrades on the bike.

Don't worry....BMW uses single wall pipes and they blue a lot quicker than double wall pipes.
