It seems like I read on a thread last week someone said they powder coated the exaust. I have jet coated the headers and would like to coat the rest so it wont rust , my question is if jet coat keeps heat in the exaust as one of its propertys wont the gasses be too hot after the header for powder coat? any insite would be great

My experience with the simple polyester powder coat commonly applied is that it will blister with heat over 350F, I don't think it would be a good coating for exhaust pipes. Might be OK for mufflers and tailpipes but I'm not so sure it would last.

If your 1970's polyester pants melt on the part at temp then so will the powder coat. Someone else may have advice that contridicts this, honestly I've never tried it.

High Yield Polyesters =not hold up

TGIC Polyesters =

High Temperature Coatings

In-Mold Coatings =n/g

Ultra V =n/g

Yes you can powdercoat exhaust providing you get high temperature paint.

Like anything else high temperature paint will prevent blistering. '

I do exactly as you suggest on all of my exhaust systems. The headers on my Willys are ceramic/metallic coated but the header mufflers are powder coated chassis black and, 10 years later, still look as good as the day they were coated. I did this on the advice of my powder coater who told me that the coating will hold up on everything except the primary header pipes. So far so good! Your powder coater will know which resin to use for this application.
