So, the update: replaced all 4 cats and she runs like a peach but a new dtc code missfire in cylinder1,2 and 3 on the right bank. Shes not missfireing like before though? Power's good and exhaust note returned however, the engine light returned after deleting the code?? the old o2 sensors were not switched. So the cars back at the dealer.
Thxs to Sparkie for suggesting Max. He was a great help and I recomend his services.
The tech suggested deleting the back cats but not sure about emmissions testing. Can our crossfires
run emissions legal with only 2 cats? I know some srt's have cats deleted but not sure about our N/A's
on the street. I'm liking the exhaust note at present with the magnaflow but with 2 cats??
