Have a Cobb catted downpipe that came off a N55 E82 (may fit other N55 cars, but responsibility of the buyer to confirm fitment prior to purchase).
It’s in excellent used condition. Cobb no longer offers these. 200 cell cat, great fitment, excellent sound without the catless smell.
$330 shipped to lower 48 + PayPal goods and services fee. Or $300 picked up metro Chicago area. Will post pics shortly.
