I have a set of OEM downpipes for an Audi S4 4.2 six speed manual. The main catalytic converter on the passenger side is hollow, still passed emissions before they were removed. These would be great for use as piggy pipes, just need to remove the remaining cats. I can do that work or just leave them in tact.
Asking $175 obo, if you want them completely hollowed out let's call it +$20
