Any engine codes, or does keeping the stock cats in place solve that? Are you running lean, or is this just an issue when removing the cats?dawgs77 said:True being a new vehicle you have a little bit of time. However when you sell it....are you going to put the stock manifolds back on...or will someone want a vehicle that is not smog legal.
I personally have JBA short tube headers......stock cats are in place.....big ole CARB stamp on them.
I don't have cams and my truck has ran a 14.1 so they don't perform too bad wouldn't you say.
