When we heard this stuff was made from volcanoes we didn’t believe it either but, we’ve just double checked and that is very much the case – just how fookin’ bonkers is that?

Composed of crushed volcanic rock, scientifically known as basalt fibre, this stuff is 25-percent stronger than conventional exhaust wraps and will withstand a pretty damn toasty 650°C continuous heat and 1100°C of the intermittent variety.

Keeping the heat inside the exhaust is a sure-fire way of upping the flow and, as we all know, getting those hot gasses out faster ultimately increases power.

What’s more this product can also cut your under-bonnet radiant temperatures in half, and that’s always good news for the longevity of the other stuff in your engine bay.
