Even if it does throw a CEL, you can clear it w/ OBD2 scanner..No big deal.

Just call Kevin. It should not. If your cat is bad, any good ECU program will through a CEL unless you disarm that or get an FVD extension (or a tubi with the same extension....for off road use only ).

Best of luck.

dreamtripper is infamous around these parts
Not a very popular choice on here, but I have a Remus exhaust with 100 cell cats and have never had a problem.
