Exhaust Heat Reduction

[nucseal]

Was pretty happy with 2016 Tri with Fuelmoto Ceramic headers and V and H Eliminator 400 slip on. But had to add Power Vision with a Fuelmoto tuner. Which it did decrease a lot of heat to my right leg.

Since purchasing my 2020 Tri I wanted to decrease the heat from the exhaust but wanted to leave it pretty much stock, so I don't have play with mother Harley. Plus I like the way the bike is running stock.

So, when I almost starting a grass fire, when I pulled off the road, because of the catalytic converter, I decided to purchase Wild Pig Exhaust Headers that are de-catted.

Than I wrapped the pipes with Design Engineering Titanium 2" Exhaust Heat Wrap. Since it was my first time wrapping exhaust, I was surprised how easy it was. Supposedly the wrap will reduce the heat by 50%. We will just have to see!

Probably will install on Thursday.

Waiting for my 17 to get tuned,had a S&S 465 cam installed along with a TTS tuner and added a Fullsac sport pipe,they remove the cat then replace the area where the cat was with two separate 6 inch long primary tubes while maintaining the stock configuration and keeping the stock heat shields plus its ceramic coated.Hoping to reduce the heat on my right leg.

Did you look into the pros and cons of wrapping? Seems like I remember reading it was fine for drag racing but not for the street?

Keeping heat in the pipes helps keep the low pressure zone to speed up the exhaust scavenging. This is simple physics at work. The key is heat in the pipes and not radiating off. That is a waste of free energy. Along with the heat shields back in place you should feel less radiated heat on your legs.

When I did the handlebars I also did the header pipe wrap with DEI titanium wrap. no spraying or soaking with a sealant. The wrap still is in great shape in six years. Granted I don't ride 10,000 miles a year but I can say it does really make a difference. There was an old guy around town when I was just a young Yamaha rider his name Red Conner an old Indian rider he would say if you young guys really want to help the rice burner run heat wrap those pipes, we all laughed young fools I guess. These are pictures before I put the shields back on. Wrapping the header pipe is just part of the heat management we have done for motor longevity and rider comfort.

+1 Jack I did a lot of research before I decided on the wrap, because I had ceramic header pipes on my 2016 Tri. I don't want deal with a special tuner and Corp Harley, so I wanted to stay with the stock pipes. I might add that I also have put on tank lift, cooling wings, mighty mites, oil cooler and oil filter relocation. After this wrap I am done with the cooling effort.

What was the length of the wrap you used?

[Fearless]

I belive it was a 25 ft. Roll and I have a little left over. Back then it was a little pricey now the cost for the titanium wrap has come down. Also I used the slim roll type clamps seems they work well

[nucseal]

What was the length of the wrap you used?

I used DEI 2" X 50' roll but I only used about 30 feet of it.

I have heat wrap if this head pipe doesn't give me enough relief,but that will have to wait until next spring.Still waiting to get the bike back then the weather is going to turn cold.

Let us know what you feel the difference is the the heat output and if it's worth the trouble. It will be interesting to know your opinion.
