My guess is, if you have TP's or a LTH, but still want a cat to pass emissions, this is a way to work once back into the mix.
Be curious to see whether a Z would actually pass a tail pipe sniffer with that single cat tho'.
Also, wondering whether it has two bungs for secondary O2's or if they stay with the TP/LTH?
Very curious to hear the xyz with and without the resonator or cat as well as see dynos...
