hi can any1 tell me if this is actually worth having on you manifold and whats its purpose thanks
 
Basically help your engine bay cool a bit by keeping most of the heat from your exhaust in the exhaust and 'increased power' because it keeps the gases in the wrapped exhaust warm and they are meant to flow better.
 
-ve pt: lesser quality exhaust will crack easily.
 
yeah i heard they could crack the exhuast mani thats why iv never done it but a know one guy thats done it n hes never had the problem
 
Personally, I really would not bothere unless its a track car....

Again, that is "personally" ... Been there, done that, and i really couldn't see the benefits even though its a technical fact it has.

But yeah like mentioned above, those are its purposes...

Can crack mild steel manifolds

Opposite actually, stainless is more brittle than mild

As dan says, don't bother unless it's a track car. Mine is wrapped and does help keep temps down a bit, i have a very thick Koyo full width radiator so keeps heat off this as well as the sump as it's wrapped up to the collector underneath

Before next year i'm going to wrap another layer on the underside where it passes the sump to keep radiant heat to the sump to a minimum :nice:
 
if you going to do it buy a decent quality wrap. The DEI and thermo-tec wraps are very good. The wrap which are woven from pulverized rock filaments are very effective although are more difficult to apply (Im using one of these at the moment on the civic).

To add, If you dont have anything shielding the manifold heat from the block you should really be heat wrapping the manifold. The front of the b-series block is prone to heat soak from the manifold (it would matter less if it was a cast iron block).
