Just got in a Sports Wagon....the previous owner said he'd replaced the the rear muffler. Looks awfully like the standard box....does the Sports exhaust have one or two thingies coming out the back. (gee that was a technical description) If my memory serves me right my TH Free Flow Lukey had one.

The TJ SportsWagon had a single dump pipe from the back end. Similar to the GTV

Cheers
