2004 Jeep Grand Cherokee Exhaust - cat delete and Flowmaster Super 44

[@1MrInc]

What did you do about / with the 02 sensor after the cat? Did it effect how it runs? Does it throw a code?

[@jasonconaway69]

Did you have the Flowmaster before you deleted the 3rd cat? If so did removing the cat make a big difference in sound?

[@salmonegg44]

have you passed inspections with the cat delete? i have a 4.0 2004 wj and i wanna do this to mine.

[@sammietha6986]

I live in South Carolina where we don't have inspections so I don't know if you could pass with the exhaust setup like this

[@TowerGoon]

Is this a 4.0 or 4.7?
