They are the best option for high-rev vehicles, and track terrors.

Should you wrap your headers?

Header Wrap keeps the heat in the pipes. This improves exhaust flow and The Scavenging Effect. It also lowers underhood temps. Wrapped headers will make a little more Torque and Horsepower than a bare metal set.

Do shorty headers increase mpg?

While more involved from an installation standpoint, headers in combination with a cat-back system will give you a measurable boost in power. In most cases, fuel mileage will remain the same or improve a bit. Two other components that affect performance and mileage are the oxygen sensor and the catalytic converter.
