If it's OBD2 then you can eliminate the cat with a straight pipe and install an extention on the secondary o2 sensor. In most cases it works because it pulls the sensor out of the exhaust flow tricking the computer to thinking the cat is working fine due to the slow changes in the sensors readings. Not shure where you can get these o2 spacers but I will get back to you on that. I no of a few guys at work who have done this and never had an issue. Im shure that XJ sounds real sweet with that Dnyomax exhaust. Will sound even better with no cat.

Rock is correct on the side post issue because there is only 4 small tabs that contact the battery compaired to the full contact of the top post. A winch draws alot fo amps.

Advanced auto has a 20% discount deal and I think I am going to get a universal cat for $125 (before discount)  and just weld it in.

I picked up a new Universal Catalytic Converter yesterday and finished in the install today.  I would have been done yesterday if I didn't run out of welding wire.  No more rattle, and it feels like I gained back a few horsepower.  When I got the old one out I could tell that the wleds inside had all busted and the it clunked around.  A lot of dust came out of it too.   ;D

I have the Dynomax on my TJ.  PO said it was the quietest exhaust, other than stock, out there. It is new still, maybe a thousand miles on it. Sounds like a stocker to me.

Dynomax muffler need to "break in", which I hear takes 3-5K miles.  Mine definatly doesn't sound stock, but you might have a differnt style muffler.  The one I have has a nice throaty sound when I get into it, but I hear the mud terrain tires more on the highway then the exhaust.
