Ceramic coated exhaust manifolds

Stainless. And they develop leaks at the welds and the accordion joints. I had to seal mine up with extreme heat manifold JB, but then I wrapped them. Even if they leak again, I’ll never hear it under all that AND the heat shields. Waaaaay cooler under the bonnet now.View attachment 14682

mare the p38 manifolds a direct swap in a defender? As in do they fit the stock y-pipe?

Had been going down the rabbit hole to do the same thing with p38 manifolds, with the heat shields. Never thought of wrapping them....

They work well. Decent margin for error as well. Just watch the thickness around the pipes and accordions. It gets pretty snug once you sandwich the heat shields back on. Only takes 50’ of DEI Titanium to do everything.

With regards to classic exhaust manifolds, we just sprayed ours with graphite. All we did was mask a bit. I’m sure it doesn’t really help with heat, but they sure do look nice now!

Terrible timing on that last post. I do not know if “they work well”

I actually doubt they would fit as I’ve never heard of anyone doing it. I’m sure someone has tried, because if they could fit, the heat shields would be a great preventative measure against manifold heat destroying the oil cooler lines.

Installed trackspec vents..I found them to be very helpful in moving out the hot air from the engine. After a long tow up the grapevine.i felt the hood which was very warm but touched the vents and they were significantly hotter to the point you could barely hold your hand on them. Coolant seems to run about 5 to 8 degrees cooler in similar conditions after i installed them.

Which Tracksepec vents are those?
