my brother-in-laws corvette has newly installed dougs headers and they look and run great, but down here in Florida theres a good deal of moisture in the air, and as a result if you park a corvette outside over night, like he has done several times he has found that on starting the car, the slip joint between the header collectors and side pipes leaks a bit of exhaust and as theres a bit of condensation the result is a fine spray of rust colored moisture for the first few seconds until the headers heat up.
now this wipes off very easily and the headers themselves are not rusting, inspection shows the muffler insert is the source.
what I,m looking for is a way to eliminate the discoloration seeping from the slip fit connection without doing something that will prevent the fairly easy removal of the side pipe for easy replacement of the insert muffler
ANY IDEAS GENTLEMEN?
