Again closing in on 200k, been noticing a smell from the exhaust and around the car while driving. No big smoking issues but when changing the oil I noticed a puddle under the muffler. Not from the top either. Wiped it and it started manifesting again. Seems one of the spot welds or two is starting to fail and causing a small leak. Seems a simple job but trying to find a full kit as I don’t weld and The tailpipe itself is long and bendy. thoughts, options?
