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?

Header with primary O2
Catalyst Secondary O2 Catalyst Resonator Long skinny pipe we call exhaust Heading to very restrictive muffler. That is the order of the exhaust. |

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?
