Are you going to long tube headers at the same time? Although the Maggies are listed as high flow cats, I've read that there's not much gain to be had flow wise just switching cats.

I'm doing it, cause i of the front cats is damaged and i need to replace it, and is cheaper to get 2 high flow cats and delete the rear to, than replace everything with oem cats.
