I have a spare downpipe in my basement, it came as part of a trade of parts so I know nothing about it. Its not a full 3inch downpipe but it opens up right off the mouth of the O2 housing flange. It has a dent on the front side of it where most downpipes get dented and another down near the catback section. Asking 100$ for it picked up from Waltham.
