Hey guys I just bought a 4-1 header off fleabay. They said it was from a 77 which is what I have. When I got it I noticed the pipes are only 1" in diameter. Is this normal for 4-1's they seem a little skinny. Also can anyone identify these?

Bear in mind the OEM pipes were usually double-walled and the internal diameter of the inner pipes was pretty skinny, relatively. Probably about the same as you have there.Dave

Those pipes were on eBay quite awhile. Never seen any others like them.Comment

That spacing looks off. Have you measured them?Comment
