Are you going catted for emissions? Aftermarket high flow cats fail emissions testing a lot on our cars.
they don't run a sniffer test and generally don't do a visual inspection in IL, either a catted or cattless DP should pass emissions from an OBDII with out a problem.
now if they do by chance do a visual, then a cattless with fail instantly, then the catted DP has a much better chance of passing.
imo passing emissions is a non-issue with a catted dp, thus i bought one.
now if you want to make some argument that cattless will really net more hp, go for it. i could care less about the extra 3 hp
