[ERA Chas]

I don't think there are "lots" of SPF Coupe owners...

So from an ERA owner, my experience is that as long as the car is not kept in damp/wet conditions and used at least bi-monthly, no harm comes to the pipes or flanges. The wrap will burn out at some bends after 3 or 4 seasons before the pipes rot. Just re-wrap. It's even better if the pipes are ceramic coated (in and out) or stainless- then wrapped. Wrap was good for 2 or 3 hundredths at the track-not a huge improvement.

The big criticism is that they corrode the mild steel. Never had cylinder head woes but I do have Manley Severe Duty valves. I stopped using wrap when I had the headers Swain Coated-over 10 years now.
