just got my jdm itr headers but look really dull but in good condition....does anybody know if polishing would work on these headers?? or any method to make it look better than how it looks now?? sorry if i posted this in the wrong spot.

 

Jet hot coat the Manifold and the shields if you have them.

As suggested, coating the header would be a good idea. You can try sanding and polishing it, but the finish will only degrade again with time.
