Default Rear pipe blued - need advice

I put a Power Commander V on my 2012 Heritage Softail Classic along with a Arlen Ness Big Sucker air filter. They set the PCV for me at the dealer based on my settings. I also have a set of Rush slip ons with 1.75" baffles. No other changes to the bike.

Today I noticed the bottom of my rear pipe is blued.

Any advice on what steps I need to take and will the bluing come off?

Can't really help you on the cause of the bluing, but to help remove it there is a product called "blue job". It works fantastic. It's a white powder that you apply with a damp applicators or micro fiber cloth and rub liberally. Take care not to scratch the chrome, but it really takes the blue or yellowish off like magic. Good luck.

No. Its not the heat shield. The slip ons do not have a heat shield. Its the bottom of the rear slip on.

I would get the dealer to shoot the cylinders with an infared thermometer.
Should'nt be getting hot enough to blue that pipe. Happen to know what your oil temp is after a ride?

A picture is worth a thousand words. How long ago was this work performed? Is the headpipe also blue? I would think that if it is running hot enough to blue the muffler then you should have already melted down a piston.

The blued area is not that large. Its a small area at the bottom of the slipon where the muffler connects to the pipe. I tried to take a pic, but at night its hard to take a good pic.

I am suspicious of the mixture on that cylinder. Might have that checked out. +1 on Blue Job.
