    LT's, ORY and CT emissions

    I'd like to pick up some pacesetter long tubes and a y pipe sometime soon, but i'm trying to decide what y pipe to get. I'd like a catted y cuz i think it wouldn't sound as raspy and it should allow me to pass emissions here in CT, but its around $200 more. What do u guys with LT's and ORY do to pass emissions?

    To pass visual inspection, you'll need cats, so get high flow cats. Well, that's how it is here for emissions/inspections. As far as emissions, you could get the ORY and O2 sims and get the PCM tuned appropriately.
