Default Exhaust Pipe Temperatures

How hot does the so called "header pipe" from the exhaust manifold to the front of the muffler get? Or...a related question, how hot would a side exhaust pipe get? Why the question? I wondered if regular powder coating of that pipe would last. Asked my powder coat guy...he didn't know...said that he cures his items at 400 degrees. I believe that cast iron manifolds and/or headers will get to the 1200 degree range. So...will powder coating last on the exhaust, or will it just burn off. How about "Jet Hot" coatings? Can it be done to side exhaust pipes? Headers only? All advice appreciated. Chuck

JET-HOT will coat almost anything! I remember a while back somebody posted pics of pulleys and some miscelaneous parts they sent to JET HOT; parts looked great and price was very reasonable. Big parts (like sidepipes) maybe not so reasonable, but I would call Todd at JET HOT and maybe get a corvetteforum discount. I have no idea what actual temps are, but I was wondering because my Flowmaster mufflers came with a heat warning - ie the mufflers get hotter than stock mufflers. MJ

I used a Raytec infrared temprature gun on my engine to see how accurate a new water temp sensor was and when I pointed it at my headder primary tubes they read between 500 and 600 degrees at idle. I think you are correct on the 1200 degrees while driving but they should be a little cooler the further you get away from the combustion chamber. Just a thought.
