Correct, deleting the 2 resonators (look like metal suitcases) and replacing with a x-pipie has no effect on any cats or O2 sensors.

There's 2 cats in the downpipes and 2 cats in the midpipe. The resonators are located behind the cats in the midpipe. They are in between the secondary cats and the stock rear section (valves). So no worries.
Thank you. Made an appointment at a local shop that comes recommended by a few friends. $300 with parts. Going this coming Tuesday
