I have a brand new exhaust downpipe for a 4.0L TJ Wrangler. It is the more-expensive California (CARB) version with the light-off catalyst in the downpipe. The part number on it is 52019435, but that may just be the light-off cat number, not the full assembly part number. It is for the 1998 model year, but should fit any 4.0L TJ that uses the same style exhaust hanger.
Pickup only.
Contact me using the Craigslist email relay contact/reply button, usually in the upper-left, but in one of the corners and let me know when you'd like to stop by to look at it.
