How to properly heat wrap your exhaust

The performance of any vehicle component is determined by one main factor: heat. Engines are giant heat-generation monsters. Excess heat can damage electronics, moving parts and severely shorten the life of your vehicle components.
Exhaust heat wraps are a tried and trusted method to manage the heat produced by your engine. They are specially designed to insulate your exhaust manifolds, making sure as much heat as possible stays inside its tubes.
Made of a weave of special fibreglass and various proprietary materials, exhaust heat wraps act like an insulating coat, protecting vulnerable components around the engine from radiant heat damage.

In this post, will show you the steps for installing your own exhaust heat wraps and maximising the performance of your engine. It’s easy once you know how it’s done!

1. Safety first
Make sure you’re wearing safety glasses, gloves, protective clothing and a dust mask when wrapping your headers. Cover up any exposed skin. The wrap material contains bits of fibreglass which can be dangerous if handled carelessly.

2. Slow and steady
Remember, proper wrapping takes time and patience. Go slow to make the wrap as tight and firm as possible.

3. Optional but recommended: soak for success
It’s always a good idea to soak the wrap in a bucket of water or spray it with water before you begin. This makes handling the material easier and reduces the number of stray fibres flying around.
4. Start closest to the engine
Always start wrapping on side closest to exhaust port (closest to the engine) and work your way towards the exhaust tip. Make an initial wrap around the pipe and secure the end with a hose clamp to make sure everything stays securely in place.

5. Keep up the tension
After the end is secured, continue to firmly wrap around pipe using quarter overlap with each pass. Remember to keep up the tension on the exhaust wrap to ensure a tight grip. After every two or three coils, use your hands to tighten up the wrap.

6. Bundle up
If you reach a point where the primary tubes come too close together to wrap individually, bundle wrap both of them together using the same quarter turn method. When wrapping the collector on the headers, avoid the temptation to skip a few turns. Try to make sure you give the wrapped primary tubes the same quarter overlap.

7. Snip and Celebrate
By this point, all tubes and turns should be tightly and consistently well-wrapped. When you get to the end, just snip away the excess wrap and secure it with a hose clamp. Congrats! You have successfully wrapped your engine tubes!
Don’t forget to secure them with stainless steel ties so everything stays exactly where it should.

Your engine should be ready to roar. You may see some light smoke emerging from the wrap when you first run your engine after installation. This is completely normal and will go away after a few warm up and cool down cycles. Remember to take care of your wraps as instructed!
