That and a cat where the y pipe merges would be VERY restrictive

i dont plan on running it that way... just when it comes time to smog it.
all the times i have had my car smoged they just poke around under the hood and stick the sniffer in the tail piece

actually a high flow cat really dosn't add that much restriction. on back to back dyno runs at my school we saw only 1hp gain on the top end

My 3.4L only has one cat but its after the Y pipe.. so that being said it in theory should get up to the proper temp.
