wrapped pipes
- Thread starter bigpoppa
- Start date
Traps water, can cause corrosion depending on what material the exhaust pipe is made from, can cause cracking from excessive heat depending on what material the exhaust pipe is made from (it may rely on being exposed to radiate enough heat to keep the temperature of the material within bounds). Having said that, if the exhaust routing takes it too close to something heat sensitive (be it a rear shock, or your shins), ya gotta do what ya gotta do. I would confine the exhaust wrap to the immediate vicinity of that trouble spot.
If it were worth doing in general, OEMs would be doing it, and professional racing teams would be doing it, but they don't. Usually, a heat shield is a better design choice for the above-mentioned trouble spots.

What @Brian P said, but just to add, usually the closer it's applied to the exhaust port, the higher the odds of damage, as it's trapping a lot of heat there.
Some stock RC51 pipes will literally deform if wrapped all the way to the cylinder, as the metal is just too thin to handle that much heat being trapped. I've seen pics where the wrap has actually made an impression in the metal, followed by cracking.
Alternately, if the wrap is kept further down the exhaust, there's often no issue as long as it doesn't get wet when cool. It's not uncommon to wrap up-pipes that run behind footpegs to stop heels of boots melting. Personally, I'm not a fan of the look of wrap, and I think heat shields are cleaner.
The other product that gets mentioned as a wrap alternative is ceramic coating, but I'm not sure how effective it is. It looks a lot neater, at least...

If memory serves me. Wrapped pipes were originally a (race) car technique to control temperature within the engine bay.
For motorcycles (at least now) it is 100% for visual appeal. For me at least I like that "rat" look but would never even think of doing this on my bike.

The purpose of heat wrap, originally, was to trap heat in the pipe, to eliminate hot spots, which causes turbulence inside the pipe. Instead of having a hot spot on the outside of a bend, the wrap holds enough heat that whole pipe evenly heats up, equalizing the flow.
Been entirely eclipsed by ceramic coating, which does the same thing, more effectively.

I've considered wrapping the pipes on my sportster as it is full of useless/dangerous fashion statements. Even if it doesn't rot your pipes, the wrap eventually looks like **** from weather, dirt, heat, etc. and after you remove it your pipes will look terrible with rust and discolouration. None of this from experience just what I see on facebook groups and why I decided against it.
