Exhaust wrap on a Stainless manifold?
bigandy - 19/10/08 at 10:19 AM

Morning all.

Can anyone tell me if there are any issues with using the glass matting type exhaust wrap on a stainless steel (welded) exhaust manifold and pipe?

I have had one made for my Sylva Mojo, and it comes within a few cm of various components (oil filter, alternator, chassis, tyre) mainly because of the lack of space in the engine bay to route it properly. I am a bit concerned about heat build up, so I was thinking that wrapping the exhaust would help a great deal.

I am aware that it leads to hot spots where the wrapping stops, but as this point is going to be fairly exposed, and not close to much, it shouldn't be much of an issue that I can see. I have heard that it can cause manifolds to crack, but I am not sure if this applies to welded stainless ones.

Secondly, can anyone recommend a good source for the wrapping stuff?

Cheers
ANdy

No issues with using wrap on SS. Depending on the SS it's better than mild steel or cast iron.

If you are that tight to things you may also want to make a couple aluminum shields. Air gaps with a thin piece of metal between are pretty effective.

I have the same problem with my Riot. An aluminium heatshield with some aluminiumised f/g attached to it has kept the starter motor and fuel regulator from frying but the engine bay is vhot - to the extent that I run with engine cover and side panels removed
