Heat wrapped exhausts?

[svsam]

what do you think?

[barwel1992]

i heard that it accelerates rust as it keeps moisture in

[svsam]

what about those kits you can get for about £100+? they must have some kind of protection added.

[barwel1992]

no idea, we use them on the race cars and considering they get removed and cleaned after every wet race the rust still builds up where the rap is applied

not saying that you can get stuf that would work though.

whats the reasons you want to do it ?

[svsam]

i think it looks pretty smart, not sure how ide work around the brackets and jubilee clips on the pipe though, that could look a bit dogey!
i like the look of that one with the custom mani on svrider.com, im sure you know the one i mean.

[barwel1992]

ohh i see, some more info hear about the water issue

I just think it looks ****, why buy an expensive exhaust then cover it up?.

[maviczap]

Nothing nicer than a polished downpipe why cover it in a bandage which will get covered in sh1te

[dizzyblonde]

looks shi1te, however according to some members on the Raptor chapter, its recommended on the rear downpipe, due to it being so close to the shock, apparently keeps the heat in so it don;t boil the shock fluid. Not sure if it works but hey, better than your bike suddenly pi$$ing everywhere and suddenly resembling a pogostick.

[andrewsmith]

No advantage, would cause most factory pipes to disintegrate quicker.

Its mainly used on the forgotten era racers with stainless pipes, stops them being ground out

DB; R&G do a shock tube now which is meant to stop the crap and reduce the heat transfer

[barwel1992]

^ i was looking at getting one of those shock things, might get one and do some testing with the heat probes from college all though to some extent it would keep the heat that the shock generates in, so would that not turn the shock in to a boil in a bag ?

Yeah not to mention they are made of neoprene (think wetsuits) which are designed to keep heat and moisture in. Corroding your shock more rapidly.

Heat rap is pointless on a bike. We used to use it to keep heat out of the engine bays of high performance peugeots running open carbs/throttle bodies to lower air intake temps.

Is that think Group B mid engined 205 monsters?

[svsam]

fair enough, autosol it is then.

pahh auto sol no chance dremmel and wire wheel and polishing wheel

that exhaust has 25k miles on it as well :D

[danf1234]

I did it on my RSVR as the pipe was sooo close to the rear shock it cooked it.

On the SV - No

[DANINPLYMOUTH]

What about those ceramic coatings you can get?
I think they look cool and am tempted to get my sprint done as it tends to cook my ankle

[madness]

It's designed to keep heat in, which can lead to an extremely hot exhaust, which I assume will conduct heat back to the cylinder head. So, it may cause overheating and possibly worse.

[johnnyrod]

More likely to make the end can hotter as that's the direction the gas is going in. As said above about the R&G thing, they're in the market of selling you aftermarket stuff so undoubtedly it'll claim all sorts of things, but covering the shock up will just keep heat in and that's bad, better to just do as said and insulate the zorst if it passes very close to the shock. Not sure the ceramic coating will keep a lot of heat in? It's only thin innit?

I use wrap on my race exhaust to prevent it burning through the bodywork (otherwise it does and has) and also to keep the rear shock protected from the temperature.

Wouldnt bother on a roadbike.

[MattCollins]

I'd need a good reason to wrap the exhaust. The disadvantages have already been listed. The TE has its exhaust wrapped solely so that I am not putting excessive heat into composite fuel tanks which cover the pipes. The pipes have been cleaned, polished, passivated and painted prior to wrapping.

[monkey]

I was under the impression that exhaust bandages were to keep heat in for additional performance?

[dizzyblonde]

As the Vraptor and the RSV are well known to boil their shocks from the excessive heat, I'm inclined to use it on the rear down pipe during the summer

Its either that or suddenly find I have a sh1tstained pogostick on wheels !!

Any other bike, I'd be inclined to say, not necessary.

[johnnyrod]

I can only imagine the additional performance is by not cooking other components or heating the intake air too much.

[MattCollins]

JR, The possibility is that it can increase header function by maintaining exhaust temperature and velocity. This has been know as a tuning tool for a very long time, however it is not a blanket rule and not a substitute for good header design and construction.
