Is there any Porsche reason not to ceramic heat coat my exhaust components from Fabspeed? I got some headers and bypass pipes for the .2

Not sure why they come polished out of the box (bling bling?). Is there some kind of strange Porsche engineering reason not to to perform this? I'd like to eliminate heat soak as much as possible, especially during the AZ summers where the roads emit an insane amount of heat.

Photos of ceramic coaitng for reference:

 

I say do it. My exhaust tips are ceramic powder coated by CCP Coatings in Detroit. They have about 8 color choices.

 

Nope! Ceramic coating is always a good idea if it makes sense for your circumstances (though it may not always be necessary), IMO.

 

There's no reason not to, but there also isn't any reason to do it. Certainly won't help reduce exhaust temps due to heat reflecting off the road, but heat from the road doesn't heat up your exhaust in the first place. Exhaust gasses leaving combustion chambers are many hundreds of degrees hotter than anything reflecting off the roads. Also, exhaust temp heat isn't a problem in 991's in the first place. These aren't F355's.

 

Ask Fabspeed. May void warranty??

Ceramic is great. Just ask them.

 

HA! I laughed, but I still love them

 

Ceramic coating is usually done to keep under hood temps down, especially when they could elevate the IAT when combined with an open element intake. Porsche's basically have cold air intakes and and "underhood" temps are not a problem.

The other benefit is keeping the exhaust as hot as possible to maximize its speed its travel through the runners and collectors. Im not sure how effective this would be on FI motor like in the 991.2.

The downside to coating and potential warranty complictaions is that you will be keeping more heat in the headers and could possibly fatigue the welds faster. However,I don't think that there should be any concerns on a FI manifold, since they are pretty robust and made to take constant abuse.

Another potential problem would be the headers location so close to the road. They are going to get hit with a lot of road debris which could chip away at the coating. They are also going to splashed at operating temperature with water which, in theory at least, potentially crack the coating. I don't know how robust the coating is, but the location of the manifold on a 991.2 will subjugate them to a lot of abuse.

 

Some good points here, I don't think I have much to worry about with water.

I'm glad to see there no real reason not to do the coating... Now, black or grey?

 

355 is IMHO possibly the single most beautiful car of the modern era.....but man, what a PITA they are.

 

I have used this product for years on race and street cars alike. Absolutely bulletproof. Reduces outside pipe radiant heat significantly and helps evacuate hot exhaust gasses more efficiently.
I could touch Shelby Cobra side-pipes minutes after shutdown.
