down pipe questions

since our downpipe, has 3 cats, is there also 3 o2 sensor's, is anyone planning a mod for this in the future, I ran a highflow cat on my pt cruiser, yet it still used the 2 o2 sensor's and performed great, would like a full engine, to tailpipe exhaust upgrade.

3 cats? I only saw 2 right after the O2... where is the 3rd? I know we legal have to run A cat, so I am wondering if we can remove 1 or 2 of the cats and leave one remaining to be legal?

ah ok, it was that resonator that threw me off, so are you going to make us a nice downpipe that will have a highflow, cat and open up the resonator as well?
