Will not fit my 2000 Wrangler TJ Sport. My catalytic converter uses a 2.5" clamp instead of 2 bolts to attach it to the muffler. Check before ordering. Does your exhaust system use 2 bolts or a clip to connect the muffler to the catalytic converter? Part #51313 (2 muffler bolts) to catalytic converter): 2001-2006 (some 2000's may use this. Mine didn't use this) Part #51312 (2.5" exhaust clamp from muffler to catalytic converter): 1996-1999 ( Some 2000 can use this. mine used)
