Also would taking off the cad converter give you that much more mileage.
as stated, removing the 3 cats you have will introduce a big host of problems, including the fact that its illegal.
the best exhaust is the stock one. really. it works just fine, and flows plenty.
the 4.0L is a tractor motor, no matter what exhaust you throw at it, its going to sound like an inline-6 tractor motor. if your exhaust needs replacing, go to the local midas or whatever shop and get regular replacement stuff. if you want to feel better about yourself "upgrading", have them do it in 2.5" instead of the stock 2.25".
