I don't know about you guys, but I don't think my 15 year old car has any little thread of a warranty on anything. That, and if you have the money to spend on aftermarket headers for our cars, then you won't care about warranties.

exhaust coating comparison. Pretty good test on a L67 crossover. Makes a good case for wrapping even just your crossover. Check out the difference in IAT values between the three. I think that wrapping is just as good as ceramic coating for the money.

Ok to prevent rust causing moisture from getting under the wrap could you like spray it or coat it with some high temperature sealant or something? And could you like wrap the whole exhaust system so that all the heat rushes out of the very back? I know that might be a problem but maybe you could make some sort of shield so that water cant get on the pipes like out of thin light aluminum. Sorry Ive been thinking a lot lately.

nothing wrong with thinking

you probably dont need to wrap the entire exhaust system, if you are really worried about it then wrap everything back to your cat. To get rid of moisture the best way would probably be to sand and spray paint your exhuast with some high-temp paint, and then wrap them.

don't wrap your entire exhaust... part of why wrapping the headers and down/Xover pipes and keeping all that excited hotter gas there is the un wrapped exhaust past your downpipe is cooler... this change in temp creates a form of suction in the headers/Xover/down pipe there by helping scanvenging and exhaust velocity.
