Ceramic coating of downpipe
« on: February 12, 2012, 03:34:23 pm »
Ive had a price to get my new de-cat downpipe ceramic coated, is it really worth it? Compared to just heat wrap? It's not a lot of money at £80, but it is £80 that could be spent else where I guess. Whats you views?

Why a de-cat DP?
Why ceramic coating it?

De-cat purely for more power and noise  : and ceramic coating as it should in theory let the hot gases escape quicker and flow out easier.

I was quoted quite a bit more from zircotec (have a good reputation) but am getting BCS to wrap mine for £50 as part of a new system I'm having  :smiley:

How should ceramic coating improve gas flow? It's pointless.
Wrapping it with heat tape will reduced heat transfer to the engine bay. That's worth
considering.

De-cat is stupid. It seriously does harm to the environment without being neccessary.
A proper 100 or 200 cpsi doesn't affect power significiently.

Ceramic coating will improve gas flow as heat loss from exhaust gasses mean the gasses slow down.

For downpipes of manifolds its worth coating inside and outside of the tube.

Thanks for that. What I was getting at in my first reply.

We do it on a lot of high spec / motorsport projects. Its not massively expensive and certainly helps, moreso on cars that have front mounted turbos or mid/rear engined where component position restricts cooling.

Think I might get this done then. Can't be bothered farting about with heat wrap.


Mike, it's a BCS downpipe I got  :party: top

You do know that if you get pulled by the police or vosa and they see you have a decat they can give you a gv9 and have the powers to take the car from you as it would be deemed unroadworthy. Just letting ya'll know

Sorry, sounds like complete nonsense. Any prove on this or at least a theory?
