So I am thinking of wrapping my exhaust pipes from the header to the stock can, in black. Cheaper than powder coating. I was wondering if anyone had some info on this. I have read that it reduces the heat output of the exhaust, but have also read that the wrap wears out the header pipes faster
Thanks

How do header pipes "wear out?" The engine should wear out long before the exhaust pipe! Wrapping the exhaust will keep the exhaust gasses hotter and make them flow a bit faster. I don't think it will make a noticeable difference, but if it looks good, then it is worth doing.

If your bike gets rained on (and I hear WA has the occasional rain :-D ), you will look like you have a steam powered bike until it dries out. Something to think about. :wink:

Yeah, after doing some research (only very, very little) It supposedly can rust your pipes due to water vapor not being able to escape when it turns into gas if there is water trapped between the wrap and the exhaust system or something like that, so if there is high humidity where you live or rains and clears often you end up with rusty pipes under that slick heat wrap.

BUT I don't know if that true for sure, just what I remember reading about/hearing. I will do some more research and get back to ya.

And also what it really does, is increase the heat of the exhaust gasses by not allowing heat from the gas to be absorbed into the exhaust system. And since its hotter increases it velocity. So essentially the exhaust exits faster and hotter with ought heating your exhaust system as much. But I don't think you will get any major gains from it, but it will look cool

Sorry for the Novel of a post :razz:

(Edit) Ah! I found a difference between heatwrap and hi-temp powdercoat and such. Heat wrap Traps in heat! While a coated header does not absorb the heat! (as much) So heat wrap is making your exhaust pipes run much hotter than they are designed to be (In most cases). I dont think it will destroy your pipes, so If you just wanna go for style go for it. I found a usefull article and while its for cars it should still apply to motorbikes as well.

Here is the link if you want to read more, as I don't have time to look up much more.

comrade, thanks for the in debth research. I actually did find that same article in my searching. I did find a local outfit that does powder ceramic coating and they were kind of reasonable. I think I will kick the idea around for a while anyway.
The part of the wraps trapping in the heat and leading to corrosion kind of has me skeptical and a little leary of wrapping. I may end up going with powder coating.

I really appreciate it :wink:
