Bought GTA Had No Cat Gotta Register Car With Proper Emission Setup What To Do?
They left all the emissions stuff on the car. Just no Cat. Its got an aftermarket exhaust and it sounds really good. Kinda loud but not to loud. I know one Cat will quiet it down a little. It will also cut horspower and torque. I was thinking about doin twin Cats.
I dont know what Ill run into so Im looking for input here.
Give me all suggestions please.

I was in the same situation, I just added a single 3" high flow Walker cat. I also flanged it for removability, You know, for test purposes.
