Header Wrap
I am about to install long tube headers and was wondering if I should wrap the headers or leave them as is. I was thinking of wrapping them to help get more heat down to the high flow catalytic converters so as to not have any emission problems down the road. So should I wrap or not, Thanks Paul.

Wrap does help with the heat. What they don't tell you is it will be a sponge for anything that floats by, think oils. It can get to the point where it is a wick for your car and be a fire hazard. Blew an engine and it shot oil on my wrapped headers and started a good fire. Caused more damage than what you would think.

and the first couple times you fire it up you'll think it caught on fire from the smoke rolling off the wrap as it "burns in".

Heat wrap will not rot a stainless set of headers nor damage the header material if done right. The trick is not to overlap to much when wrapping (only overlap 1/4"). Also, don't wrap the cats! As for me, I creamic coated the headers and wrapped the rest of the pipes. No heat problem at all!

It's NOT just a coating, the ceramic keeps the heat in the header-that's what it really for, looks are just secondary.

I paid $125 for my B&B shorties to be coated inside & out, and I'd do it again on any other vehicle.
Where exactly did you get that deal

Reduce temps with a good ceramic 250 - 350 on the high side.
Wraps will rot the metal no matter what it is. Even with the silicone spray you will still hold moister under the wrap AS well retain moister within the pipes themselves. You also run a much greater risk of cracking your SS header with a wrap. Not to mention wraps create hot spots in the header causing thermal fatigue and heat soak that will eat you alive.
