Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Exhaust Wrapping - a good idea?

Ok so here is what I found and I now wrap all my exhausts

The smoke is due to a little burn off of the lava rock quite normal

The under bonnet temperature will be reduced as the gases remain hotter and are expelled through the exhaust

Now here is the science...

Engines and fluid dynamics come into play and basically...the exhaust gases on a non wrapped exhaust are expelled and immediately the hot gases begin to cool in the manifold and when they cool gases 'get more dense' and this effects the extraction and thus the gas flow .by restricting or resisting flow..

On the other hand a wrapped pipe stays hotter and gases remain hot and therefore less dense and flow is improved...

Also an added benefit is that the 'noise or ring' of the pipes is muffled with the wrap..

I have noticed performace improvements dure to lower under bonnet temps and also hotter exhaust pipes...
