[SuperCarrera]

One other item of "confusion" regarding this issue -- I've heard both sides of the "best exhaust flow for my car" theory from several different people.

One "group" has said that, by restricting the airflow a little more (such as with this 2.5" muffler), I will gain low end torque and acceleration but may lose some top end speed/power.

The other "group" says that, because my motor is supercharged, it does best in all RPM ranges with the minimum airflow restriction at all times (so header tuning does not apply) and I should use the largest size, most free-flowing components through-out.
