I was told at the Party from MOPAR that stage 2 and probably stage 3 will only need the MOPAR dual system which he said was 2.5"! That would make 3" nice but not needed for performance! Stage 3 gets rid of the cat so a bigger down pipe would be the only restriction. For Stage 2 the cat would be the restriction as I believe the present stock system does not choke the flow from the cat! I would say for any muffler work based on performance go with a big down pipe and get a high flow cat and 3" SS outlet pipe or pipes on a 2.5" cat back system. That should fit on a lowered car and a 3" dual outlet cat back system for sure would need at least the spare tire removed!!
