Put black tape over your check engine light. You're done.

Or do what Mitsuguy recommands because the SRT intake is questionable and removing catalytic converter is a bad idea. Those people that are around this board when 2nd gen GS first came out and SRT released their intake will know that intake is not without controversy. If you really do feel like screwing with your car install their torque converter while you at it, it will make you feel like your current problem is just a little rain drop compared to what's comming.
