just wondering if anyone knows much heat wrap is needed to wrap a 4-2-1 manifold for a polo gt

A lot it's pretty deceiving think I bought around 15 metres and had enough to go all the way down to the centre join. Better to buy to much than not enough.

ok great and just wondering who has done this and whats you experiances with it as i have read pros and cons from using it with the most concerning being that of manifolds warping and cracking

I am thinking about removing my wrap and spraying the manifold black. I have had it on for about a year and was wondering if the rust and water will be eating it up.
