I see. Well, if you remove the pre-cats, I can't say for sure if it will throw a SEL but its not going to add any performance. You will want to make sure to keep the resonator between the main cat and the muffler as removing it results in a very annoying sound above 2000 rpm. As for dealing with the muffler, you could always look into replacing it with a muffler from the last gen camaros/firebirds (not the new one). It will take some modification to the piping but will give it better sound and slightly better flow. Hope that helps a little.
