Better Performance & Gas Mileage, really?
A. Virtually all factory mufflers are designed to be quiet. Power is a secondary concern. This means you typically can reap performance benefits by swapping mufflers. How does a muffler improve performance? At the most basic level, by increasing exhaust flow. Virtually all specialty equipment mufflers are less restrictive than stock-style units. Because more exhaust can pass through at a given time, backpressure in the exhaust system is reduced. Some of our mufflers even create a scavenging effect.
