hey i was curious will the rb true dual pass ct state emissions? i noticed that rb sells a presilencer thats a direct cat replacement. but the header to the twin presilencers is said to be "not emissions legal in the state of california" even though it has the o2 sensor bung. my question is whats the difference between the stock exhaust manifold to downpipe into a presilencer then the y-pipe and mufflers compared to the dual header to twin presilencers then back to the mufflers?? anyone with CT emissions experience or advice on how to pass the emissions(lean it out?) hit me up. i just bought this exhaust ...$$$... and dont have a stock unit to test with. PM me or call on the weekend (860)834-0843 my name is Lance. thx!
