how do you secure heat wrap
 

Have the roll - but what stuff do you use to secure the end of it on the manifold/downpipe?

Lock wiring looks the neatest or you can use hose Clips or metal cable ties.

Metal cable ties off Ebay cost me £2 for 5. Ideal.

scoobyparts supply the cable ties for the heat wrap wet the heat wrap to make it easier to put on

i would also advise soaking the heat wrap so it is ringing wet and then fit it using metal cable ties and when it dries out it shrinks and tightens up

Steve, snapstraps do the job neatly and effectively
