Has anyone else with the i4 deleted their second cat in addition to the pre-cat delete? I was thinking about removing it and just adding in a long resonator in its place, but am curious if there are any real gains to be had.

I have a CVT, so I had an exhaust shop weld some extra flanges so I could put 2nd cat back in place if I wanted to. There are slight gains, but they are minuscule.
