Review on MAHLE Original F31661 Exhaust Flange by David Baer

Outside diameter approx. 53 mm. The old seal pulled from the car was about 64mm long. At the bolts, the 2003 Corolla's plus side springs fit into the weld nut instead of standing and grabbing on their own, making this repair not as difficult as it sounds compared to '90s Hondas. Update: This fits the mid pipe to the muffler. Attachment point for Integra 3rd generation. There are no noticeable exhaust leaks. I've since updated my review.
