You will definitely see more gain by losing the secondary cat. I do not suggest removing the resonator because the stock resonator has the crossover pipe integrated into it. That crossover balances the two banks. Just my suggestion.

If you have K2, why not take off both cats and leave in the resonator? This is essentially what most folks would have running the LT headers right? I assume with the K2 programming you'll pass emissions tests either way...and without the program, you'd fail either way. Why not go for the extra horsepower?

I've been told if I'm in a state where the emissions test is the OBDII test, passing emissions should be no problem with a Kleeman tune and cat delete. The secondary O2 sensors need to be plugged in for the ECU to see a signal, but it won't matter what the signal reads.
