Heat wrap
My exhaust is nearly done, and I'm considering wrapping the whole length of the system with DEI 2" titanium heat wrap. Good idea? Headers are already in place so I won't be doing them.

Have you thought about a Jethot (ceramic) style coating instead?

I think a few factors play into it. Living in FL, we have a super low dew point with very high humidity. Just sitting in the garage things get moist. But I agree with you that while youre driving is probably not the time its corroding.

I wrapped the 4" exhaust on my 95 Dodge Cummins truck from the turbo to the rear axle back in about 2000. No rust issues. On the Miata I did the headers and the exhaust pipes to the xpipe behind the transmission about 4 years ago, again no rust issues. Me thinks the rust issue is more an urban myth than anything. I can see how Florida's high humidity may change things on a vehicle not driven frequently though.

Or no longer an issue with modern alloys?
All the headers I've wrapped were stainless steel and I used the pre-wrap prep paint, then followed up with the sealant paint over the wrap. ...then again...I've never kept a toy over 2 years and they are always fair weather toys unless I just plain got unlucky on a ride/drive.

Just some additional information from someone who experienced such things first hand.

Wrapped my motorcycle exhaust about 10 years ago, kept my leg from getting burned, but I rode from march till november in NYC in all weather and the pipes lasted 4 years. They didnt fall apart but they were flaking rust everywhere when i took it off. It was mild steel, painted and wrapped.

Ya, I'm going to pass on this idea. I'm in SW Ontario and we have wild changes in weather and humidity. Maybe I'll just go with some heat paint, and some clamp on heat shields.

I really do like that stand-off exhaust insulator that I installed when I first finished the swap. Car interior stays comfortable and I've never had any fuel tank pressure problems that others have described in the past. Perhaps the best results for 12 min worth of work under the car.
