Thread: Heat wrap for defender exhaust. Questions...

I can not answer C but...

A = Not an issue at all
B = personal preferance is my guess

I have a 4" full system on my 93 supra wrapped in ebay glass wrap just take your time wrapping it up I used tie wire (I am ex concreter) instead of mig wire to hold it all inplace as the wrap went on, After removed the tie wire and used stainless bands similar to cv joint clip's to clamp it to the system as for it not to move.

Work's a treat.

I was think of using stainless hose clamps same as is on my turbo hoses.

Google is your friend on different types.

I bought stainless cable ties to secure mine. (Haven't installed yet though).

CV boot ties (also stainless) are a cheaper option.

Hi guys,

I was also thinking about wrapping the exhaust on my Puma as I got hold of some exhaust wrap.

Would it increase the engine temperature and thus make the radiator work harder?

No, not at all, the heat has already left the engine. If anything it might help reduce engine bay temperatures, by removing a radiant heat source in the engine bay, which will in turn improve cooling.

Thermo-Tec Exhaust Insulating Wrap

Thermo-Tec Insulating Wrap gives Safety with Performance. Tubular manifolds by design produce a vast amount of heat in the engine compartment. This increases the possibility of electrical/ignition components not working effectively and promotes a higher risk of fire (if any combustible material comes in to contact with the manifold), not to mention the likelihood of severe burns when working on the engine! By wrapping your tubular manifold with Thermo-Tec insulating wrap you can overcome all these risk factors. Thermo-Tec keeps the heat within the exhaust manifold so the exhaust gases have a much higher velocity, this induces negative pressure (scavenging) which increases air intake flow, resulting in better performance & economy. Technical Notes: Thermo-Tec heat wrap - which is race & rally proven - comes in rolls 2” wide x 50 feet long and moulds to the contours of the manifold. Being a Silica based fabric (it does not contain asbestos or carcinogens) it is unaffected by oil or water, withstands temperatures up to 1000 degrees Celsius and reduces under bonnet temperatures by up to 70%.

Keep in mind that the wrap will increase the rust rate of the exhaust as it will trap moisture and dirt, especially off road. It may be a better option to install heat shields over the problem areas to help block/reflect the heat before it reaches the cabin.
