You're not going to leave a lot of power on the table by keeping the stock catback. I use an SPT single catback with 450whp. People put melon-launchers on their cars because they like them or have a hard-on for Fast and Furious. That kind of flow really isn't needed until you're making a hell of a lot more power.
