Hey Feets... here is an FYI...

I have an 86 Mustang SVO that we recently did some mods to.. larger turbo, 4 into 1 header, 3" downpipe and etc..

When we first fired it up, the temps coming off the exhaust was incredibly hot.. 1100+ degrees off the header, 800+ off the downpipe..

We ended up having the header, turbo exhaust housing and downpipe ceramic coated and it made a world of difference regarding the under hood temp..

The ceramic coating not only looks better, but it was cheap too.. less than $200 for everything... well worth the money spent..

BTW.. thanks for the write up on the fan, when and if the HHR fan craps out, I will be re-reading this thread..
