You could ceramic coat the downpipe but that would be expensive. For a track only car you could possibly wrap it, but on a road car it would get wet / soggy / nasty very quickly. Heat shielding barrier in between the exhaust and pipe may be an option, but there's not a lot of space!

I asked about getting the modified manifolds ceramic coated a while back. Although I haven't got a quote yet. So it may be an option to do the lower sections too.

Interesting - I was planning on getting my tubular manifold / turbo housing / downpipe done at some point, they are considerably cheaper...

Thanks for the suggestions. The Maldon one is my current location.

That seems a very reasonable price! Could the ceramic coating be a good alternative to normal (paint) powdercoating on wishbones and other under-car parts? |

Powdercoat is better at protecting wishbones and so on and still cheaper than high-temp ceramic coating which is really a heat barrier thing. Your wishbones won't be seeing 900c on the regular unless something goes *very* wrong. Ceramic is definitely better than 'high temperature exhaust paint' however... |

Man maths... Perhaps if the full exhaust is ceramic coated there will be no need to upgrade the gearbox cooling

I think you will need to do that anyhow. I haven't got anything behind the downpipe coated,but I don't think its radiant heat from the exhaust only.
Edit: well, if you decide to go bananas that is.

I just dropped off my new center panel guages.  It's been a while since I've seen this. Love the engine bay 
Image Upoader just crashed, so I guess thats it for now.

Angling the radiator back allows plenty of space for a massive 4" silicone elbow to go down into the cool air flow.
We may ditch the bonnet latch arrangement and have QR pins.

Modified CompTech manifold on the drivers side. Now angles in more to clear the steering shaft. Both sides are extended to the same length. This moves the bulk of the connecting flanges lower down for more clearance.
Passenger side is left alone and just extended to match the other side...
Looking up from under the car...
It was decided to go for a 2.5" exhaust system. This will apparently give an ideal back pressure for NA use. It also allows a smidge more room next to the gearbox and butterfly brace going in. Once it's all done we will discuss ceramic coating costs. At the very least this will cosmetically improve the manifolds as they are used items from USA. Perhaps a subtle dark grey will look ok.

We also chatted about fabricating the sump guard again. The current thoughts are having strong support brackets / tubing coming down from the chassis rails to a removable plate with a 45 degree kick up angle. So for now will will just get it on the road but with a view to moving to a dry sump system next spring. I'd like to get some use of it while the weather is still nice!
The bonnet will have a simple oval cut into it for the Holley. QR pins to be added. May use my spare plain bonnet without the vents. The front bumper will also be switched to a plain unvented one at some point. Plus the front badge will be going. So less clutter.
Once the exhaust is finished we can move onto the small jobs like plumbing and little fabrication details like brackets, shields, etc. It's been a slow process, but inching closer.

Sweeeeeet.
If you fitted blocks to the rear of the bonnet to lift it slightly, as people used to do on the fast Fords running big power to get some extra cooling, would that give you clearance for the holley intake?
