MRC Racing Exhaust Headers are high-quality performance Headers that connect easily and directly to your exhaust and offer the single greatest power gain to any vehicle.  Exhaust scavenging allows the cylinder to vent exhaust gases more efficiently (non-existent in a stock exhaust manifold).  This phenomena is the basics behind the increase in engine performance generated by a header.  Consist of 1 5/8th Primaries - a larger primary provides more power and more flow with an improved sound.

These headers are the biggest single power gain available - expect an increase in power throughout the RPM range with the best gains at higher RPM. Every header comes with gaskets needed for installation.  Stainless Steel for a show-quality look and longevity.
