Has anyone ceramic coated their entire exhaust?
To be clear, by entire exhaust, i mean header, overpipe, front pipe, and catback/midpipe & axelback.
I'm wondering if any one has had heat issues such as power loss, or melting cats.

I know of a few people. Melting cats is a different issue entirely, but you shouldn't with a good tune.

The main reason for anything behind the overpipe would be corrosion control, not actual performance.

I'm more concerned for increased exhaust temperature issues than anything.

Than coat everything near the engine - forget about the catback. On my 04WRX my exhaust manifolds, crosspipe, uppipe and downpipe are all coated and ported. It definitely helps. Turbo is not , but I have blanket and a heat shield and my TMIC has gold heat reflective tape on it. Anything to stop heat soak.

I have done the header, over pipe and cat back. I need to do the front pipe and I am done. The performance gain is minimal by doing the catback..so I don't think will be value for money type thing. I have done more for the looks of it.
