So I have a 2009 and am totally catless with LTH and I am not able to pass emissions at the moment. I bought the car used from a man in Mass and he said he didn't have issues passing but for some reason I am getting 2 or 3 (I cannot remember) unreadies and I think GA you can only have 1. For those who are catless with emissions testing in their state, what have you guys done to pass? It currently has a Bren Tuning tune from when I bought it.

you won't pass with your current set up. Your tune turned off your o2 sensors. You need to have them turned back on or you will never pass. Once they are turned on most likly you still won't pass because there are no cats. You can try spacers but I have heard mixed things about those. I have heard of a few members who where able to pass with the sensors turned on and catless. I wouldn't count on it. Most likely your only way is to buy high flow cats that can be removable via test pipe option. Get your o2 sensors turned back on and you should pass. Then bolt test pipe back in go back to original tune good to go.

Thank you. Now where would the best location be for a high flow cat in my setup? Just after the LTH's? Thanks for your help

yes most likley you have a midpipe with your long tubes. That's where you want them in the mid pipe after the long tubes.
