Can you, yes. Should you, no. You wont gain any horsepower and its also illegal to do so...

mrangelo Hello Guys,

Actually, for some reason the Flowmaster website only shows a 60 series available for TJ 2001 which I dont understand why, the Jeep is 2.25 center in x offset out, they sell a Super 44 in that configuration, so why apparently the dont sell a super 44 for my TJ? I checked on Amazon, 4WD and other online stores and apparently there is not a Super 44 model for a TJ 2001.

mdm The OP is in NJ so CA emissions laws probably don't impact him.

My Sport is an 03/2000 Colorado Jeep without the mini cats. I've seen 2000 4.0L TJ's with the mini cats (california builds)...
I'd agree with that one since California has a different emmision standard than Federal.
