THe Maremount part # in the ad means nothing to me. The Mopar Part # is 1675 698. The headpipe is 15" long. The part is same for Dodge 6 cylinder.
Try quizzing the seller…how does he know it is for Ply, Dod 6 cyl? Then youmay just have to trust him.
Looking at the pic, it looks correct to me, being that my car is a flat six, this thread is confusing tho as the writer has the title as “flathead six tail pipe” which is reality its the “headpipe” or “exhaust” pipe that he wants…
