Re: ceramic coating and 2-piece EM...

Jim, Phil and other listers Hi,

I will agree that the CC treatment may sound a bit dangerous for the turbo
but a CC treatment for the outside of the exhaust manifold, even a DIY one,
will most certainly assist in reducing the under-hood temperature and
increase the exhaust gases' temperature at the same time.

My only other concern is whether it is safe for the turbo to receive further
increased exhaust gases.

Any comments?
