These are the Stainless Steel pipes sans the heater tin. I bought these from a respected vendor here but never installed them as I found a set with heater tins for a good price.
These have a slightly bigger ID than stock and flow better. From the pics you'll see that I started to polish up one of them but it is tedious so I stopped. But you get the idea that they can be made to shine.
At some point someone had done some repair to the stud ears with a couple being replacements.
Please see pics.
