You will need to leave the emission system and components intact; the oxygen sensors and catalytic converters for legality purposes. You can purchase a cat-back system from the numerous on-line aftermarket vendors; Summit Racing, JC Whitney - to name just two. Name brands such as; Corsa, Magnaflow, Flowmaster, Gibson - to name a few.
