Does decanting the head pipe reduce heat?

Thank you for this answer. That was my biggest concern.
I have purchased a set of SE slip-ons, SS breather system and a power vision. My goal is just to get the most out of the bike as with everything that we use for touring we're pushing the 1800lb range. Hopefully that will do the job.

Decat the header,put aircleaner on bike.
Put your powervision tune on it.leave stock mufflers on bike,will not be any louder cruising down highway.
will get louder when you are passing or getting on it.
your wife will be so much happier,
did the same on both my last two bikes,wife happy not burning her ankle on right side.

On my '10, decat, stage 1 breather, PV tune made a huge difference, not only for Maureen, but for me as well. Instead of trying to wrap underneath the heat shields, I broke down and ordered ceramic lined headers.
I am surprised actually, that Harley seems to ignore this issue. Hopefully they addressed it with the M8.
Radiant jug heat has been with us since the shovel, but free flowing exhaust and normal tunes kept pipe heat manageable even in stop and go traffic. True duals of the old style took the rear jug heat over to the other side and down under the passenger. But using a single cat in the coupler is cost efficient and we all know that Harley bent over for the EPA and put innovation aside.
Of course, not only the super lean EPA compliant tunes increase heat, but the inexhaustible race for having the biggest baddest engine drives heat increase. If you think the 103/107 is hot, just wait til we see the 130,s. That's a joke.
it is not a Harley issue alone. Some designs lend themselves to heat near legs more than others. I've ridden somebody metric and sport bikes, we are not alone. Soon, the smaller turbos will appear, hopefully before I'll looking for a way to pin a playing card into the spokes of my new electric scooter.

The best way to serve a fine red wine is to decant it. Put into the decanter and allow it to rest for 15 minutes before serving. This allows the wine to breathe. But, does very little for Motorcycle heat.

i saw that in the title, but ignored it because I did not have the cleverness of your response.
We make a product called a crotch cooler that redirects the air flow ..

Throttle back, dude. You got some very good answers and info here.
