Should I wrap my pipes with exhaust tape?

Personally I've never felt the need to do so.
But found this article that clarifies a lot for those who consider doing it

Quote:
Question: Now that bobbers have displaced choppers as our leading form of motorcycle custom, I see more and more bikes with exhaust tape wrapped up to the cylinder heads. I suppose some people dislike the way chrome or stainless steel exhausts turn blue, although I love the brownish-blue color of my Triumph Speed Triple’s pipes. Considering that the hottest area of a motorcycle engine is the exhaust valve/port area of the cylinder head, it would seem to me that wrapping pipes all the way up to that area will reduce the head’s ability to cool. Am I missing something, or can this lead to issues down the road?

Answer: Pipe wrapping comes from NASCAR, where its purpose was to cheaply reduce temperature in well-filled engine bays. Its current use on custom bikes is a visual theme that builders apparently like, but it has no function. If you walk through racing paddocks at MotoGP or World Superbike events, you will see no woven fiberglass tape wrapped around pipes.
Some years ago John Wittner (builder of Battle of the Twins Moto Guzzis) warned against the use of such wrapping on titanium pipes, which overheat, react with oxygen, and transform into a mass of loose yellow flakes. During the two-stroke era in 500cc Grand Prix, bikes appeared for the Japanese GP with pipes insulated by various means. This was done to meet new noise regulations. Later, it turned out to have undesired tuning effects so its use was discontinued.

I don't know about tuning effects Makis, but the one time I used wrap, I found out two years later that the pipes had deteriorated to the point they had holes. The metal had flaked off so bad I had holes in the pipes. It wasn't a Ti system, it was whatever normal exhaust pipes are made of. Another thing I hated was the wrap begins to deteriorate too, and that caused dust and fibers from the wrap to get all over the place.

I wouldn't use it.

I have had my exhaust wrap on for many years, no idea what the pipes are like underneath it!
It will give benefits on some engines, the increase in temp speeds up gas flow and can give a marginal increase in power, i believe this is not the case with the rc however i wrapped mine to keep heat out of the battery and radiators which are very close.

as far as your sig goes..... if you are attacked by a mob of clowns....go for the juggler

It's kinda retarded to do it that far back on the mid-pipes.

To get any real benefit for scavenging or heat reduction it would need to be closer to the head.

It's not retarded at all if you're doing it for aesthetics.

The only reason I can see for people doing it is to hide road rash on their mid pipes.
So they're covering a little damage with a lot or eyesore.

Don't do it!
