1. The stock exhaust of the 3.6L is 2.25" - does that NEED to be changed to 2.5" when adding a SC, is it recommended, or does it not make any difference at all? I'm thinking more air in requires increase in exhaust piping, but WTH do I know?

2. What catback systems have you used with your SC?

3. Whether your exhaust is OEM or aftermarket, does having a SC cause it to sound significantly louder and/or deeper?
