Another F430 manifold quandary!!
Discussion
I also think the capristo brackets are a step in the wrong direction, i had mine on around 3 weeks which resulted is blown manifold gaskets.
From an engineering point of view the capristo brackets put more strain on the manifolds as they hang the system from the bumper brackets.
As a side note i am on MK2 manifolds and have done nearly 20,000 miles with apart from the above gasket issue have been just fine.
But if it was me i would go AP manifolds with Zircotec coating on them.

I got a set of AP manifolds last May, I had them ceramic coat by a company in the U.S. Prior to posting.
The coating burnt off after about 50miles (I know they got some proper heat into them after having it flat out admittedly
) and I ended up having to get exhaust bandage fitted. The U.S. Company that applied the coating gave me a full refund. Not sure why it failed? Thermal expansion? The coating was plasma applied and supposedly the same as used on race cars over there.
Be interested to hear how the zircotec coating stands up.

Sorry the pics are upside down!
Ps.
I have tubi back box + test pipe fitted also

I understand from Zircotec that their method is unique, there warranty is 3 years and will take temps of 900 degrees C, no road car will ever get that hot, their words off course!! hoping they stand up, if they don't, like you have done, I will inform others so they are armed with all the right info.
Again, I need to thank Voicey, he just go a message to me in time for me to change my order to supply only from the U.S. and coat over here at Zircotec.
Fingers crossed!!

IIRC the US coating company claimed their coating was good for 1300 C?
The car had already completed a few heat cycles after installation whilst in the care of the indy doing the work. There was no issues apparent at this stage, it was only after a period of very high speed running when I had collected the car where the coating failed.
I noticed when i pulled up to see smoke coming out of the engine bay with smell of burning paper, quickly reached for the fire extinguisher!! Thankfully it wasn't needed.
I understand there will be some expansion but if the coating can't cope with that then there isn't much point in it. Hopefully Zircotec's coating will have better results, bear in mind i only had issues after the car had been at sustained high speed/revs for some distance, was perfectly fine with normal running.

I spoke to Liz at Zircotec this morning, guided her to this thread, she new straight away that the white coating was painted on, she talked in detail about their coating and again pointed out that they are the only company to guarantee race cars as well as road cars, I don't want to quote all she said verbatim but she did mention an Aston Martin Race Team that is still using their coating in to it's 5th race season!!! she called it "coat and forget" so lets hope, the expansion point doesn't hold water either. the photos show complete loss of coating all over.
Has to be said, the lagging looks as good if not better than the Capristo nappy lol

The manifolds shouldn't be triggering the CEL. What code(s) are you getting?
Car's at DK Engineering, will have the codes MondayP0420 (0420) Catalyst System Efficiency Below Threshold
P0430 (0430) Catalyst System Efficiency Below Threshold
Maybe I need new Lambdas or maybe I need new Cats - or both (sound expensive)?
I had that cel code once in germany after a days high speed running on the Autobahn, car went into limp mode. Was ok after being allowed to cool down, clear the code and never came back. Only time I had it. (With AP manifolds, OEM cats and Tubi back box)
I get the same codes now after about 50 miles due to deleting the oem cats (Tubi test pipe fitted).
I have fitted some mini cats in front of the post lambda sensors but still get the cel after about 50 miles. Will be having a power map applied and cat efficiency codes removed at the same time in the near future.
