I have a complete xj exhaust from the header back. New O2 sensors, performance cat and a Flowpro muffler all in great shape. It's about $250 worth of parts that I don't need as I have a WJ now.  I have the donut seal too.  Bolt it on, put a turn down or a tailpipe and you have a great sounding exhaust that will last a long time.  Make me an offer.  Local pick up obviously. I'm in Zip 49330. Might meet up if possible.  xjarcher@gmail.com
