Long on power, easy installation, and 50-state smog legal—that's the formula behind MimoUSA Performance Headers. With these custom-engineered pipes at your truck or SUV's side, top-end horsepower and smooth sound are all in stride.Your factory exhaust manifold also known as "headers" is designed only in part for efficiency and power. As a result, maximum exhaust flow (power) is not achieved using factory headers, regardless of other performance exhaust headers modifications. To maximize flow and power, a better designed headers are required.

Maximize Flow to Maximize Power

These headers increase flow and power by using larger diameter tubing and an equal length design, meaning all pipes leading to the collectors are the same length. This design means that as each cylinder fires, the exhaust gas pulse released arrives at the collector following the previous pulse in perfect synchronization, creating a perfect, uninterrupted exhaust gas flow. This smooth flow means MORE flow and more power.
