Thanks for all the replies. They made me think of different aspects of this install that I had not thought of beforehand. It definitely does hold the heat in all the way from the head connections. I hope the pipes don't crack from heat at the y connection but I am going to leave them this way and see what happens. If it cracks then I will replace and report back here. I wouldn't claim warranty there if I created a condition that caused it. By the way, the two nuts that hold the front header pipe flange to the head and the two for the rear were way under torqued (after only 1500 miles). I am glad I removed the chrome covers and checked them before wrapping. Any moisture that gets on it will evaporate quickly I can tell you. I thought the header pipe was made out of stainless anyway. If I let it sit outdoors in the rain then it may be an issue but my truck will be parked outside before this bike will. The next step is to monitor temps with the Powervision (from my 14 streetglide) and see if any temps are different. I had it connected on a 200 mile ride and saw engine temps (not coolant temp) of 290+ before the exhaust wrap was installed. I would never have know those temps were at that value if I had not monitored it. I'll get back on this info also.

 

 

 

I too have wrapped my pipes on previous bikes and race cars for years with no adverse effects. And plan on wrapping my current '18 SG for this same reason. It is good to know what results I can expect; thanks OP for the write up. Question for the OP; the wrap you used looks like the titanium type, correct? If so that is "rated for 1800 degrees" verses the 1300 degrees of the ordinary kind. Also, what width wrap did you use?

 

CWOFOR, I used a 50 foot length 2 inch wide roll of DE Titanium Exhaust Wrap (53.99). It says it is rated at 1800 degrees direct heat and 2500 degrees intermittent heat. I also had to buy a pack of 8 inch stainless straps (16.99) and a package of 14 inch stainless straps (11.99). I did not use all of them because I wanted spares just in case. I used every bit of the 50 foot roll though. I thought at first 25 foot roll would do it but I changed my mind at the last minute and went with 50. Make sure to soak it under the faucet first and pull it tight as you go. I have ridden it now for several hundred miles and it looks like it is going to stay tight. No odors at all now. I notice no excessive heat anymore at a redlight on surface streets. All the materials were hanging on the wall in O'Rielly's Auto parts.
I think the real test will be time and miles, but like Bumbandrun said: 73k miles on a TC and wrapped exhaust the whole way. Really encouraging. Thanks all for the re-enforcing feedback guys.

 

Thunder header under there somewhere- .I have been wrapped for a very long time.
No cracks in 5 years and a whole lot of miles.

This is a great thread. I’m giving this some serious thought, as my ‘17 Ultra Limited is nearly setting my right heel on fire.

To those that have wrapped M8 pipes, and then installed the heat shields over the wrap:
- did the wrap appreciably reduce heat on your right foot?
- has anyone experienced any pipe cracking or rusting?

Did anyone try this stuff by putting it under the heat shield? Maybe I should just wrap my boot in it.Thermo-Tec 13575 Adhesive Backed Aluminized Heat Barrier, 12" x 24"

 

Damn! I thought my foot was hot!!!

 

lol You may need to wrap your foot with that stuff!
