Default Exhaust Wrap

I hate heat shields so thinking of wrapping header pipes on a set of RH TDs but don't know anything about it and would like to hear from those that have been there, done that.

Would you do it again? Have you removed the wrap? How hard is it to remove/repair if damaged? How does it hold up to weather? How did you wrap around the clamps to the slipons, or were they left exposed?

Any do's or don'ts would be appreciated.

The metal fatigues and rots when you use the wrap. It's basically for racing to enhance exhaust flow.

Thanks, but I knew that much. Am interested in hearing from those that have installed the wrap on street builds. Like, how long does it take for the header pipe to "rot"?

I responded before the photo downloaded. How long did it take for that damage to occur? Why were the heatshields wrapped? Could that have contributed to the problem? I want to rid myself of heat shields and wrap the head pipes to cover up the three steps. I suppose I could have the head pipes ceramic coated and leave the steps exposed. Hmmmm, wonder how that would look?

They were V&H pipes and it took less than a year. The wrap holds in the heat and moisture and that's the cause of the de lamination of the pipes. The ceramic coating is a better thought for sure.

That's a good question. Seems like wrapping with the heat shields on would not be a good idea. I still don't understand the whole "trapping moisture" think. Pipes should run hot enough to burn off moisture, no?

as i cant see the pictures posted i will post the images of mine when i wrapped my V&H short Shots, the front header snapped off just below the head clamp and the rest of the pipe was delaminating all the way were the wrap touched the pipes,
they hold water very very well as when stationary from riding in the rain you would dissappear in a cloud of vapour

broken header

you can see the the delamination starting here round the O2 sensor

Pipes 11months before hand

mind i do ride in the snow

I guess the main question djl posted was why wrap the heat shields too? Most people would remove the heat shields and wrap the bare pipe. Perhaps that was a contributing factor to the early failure of the pipe. I know a few people that have wrapped theirs and haven't had any problems in well over 2 years. Not saying that it will or will not cause pipe failures, just an observation on your particular case.

I wrapped bare pipe on a metric and issues similar to my bob, the pipe plastised and started to deform, mind I do live a wet climate which possibly doesn't help
RB racing had an article on their site which explains the whole process better than I can

We also figured after the barepipe failure/deformation that wrapping the shields may have helped stop the issue by adding and air stream as minimal as it may have been but nope

I checked the RB Racing website but couldn't find the article you referred to. Can you provide a link to the article?
