The Megan Racing Head is a steel head made from T-304 grade stainless steel. Each Megan racing head offers Mandrel tool bent flanges and tubes from a CNC machine. All Megan racing head parts are tested to ensure fit and performance meet all standard targets, and every Megan racing head comes with a one year warranty. Megan’s All Racing Header is a replacement for any factory header on a vehicle. All of Megan’s racing heads, with the exception of the Acura Integra GSR, come with the outlet that bolts directly to the vehicle’s factory exhaust pipes. The Megan racing head for the aforementioned Acura offers a two-and-a-half-inch JDM power outlet. All other Megan racing head parts will bolt on directly and none come with the exhaust manifold gasket. This is a recommended replacement when the new head is bolted on.

These heads are available for the 1995 thru 1999 Dodge Neon with the DOHC finish. This is a 4-to-1 design that provides high power and a two-and-a-half-inch outlet that can be found for around $150 each. The Honda Civic is equipped from 2001 to 2004 with the EX version and can be found for around $150. The Honda Accord is compatible from the years 1990 to 1993 and is available for $170. The only supported Infiniti model is the G35 from model year 2002 to present. This model offers a 2.25-inch outlet with power gained due to increased airflow and can be found for around $330. The next most popular vehicle model for this system is the 1995 to 1999 Mitsubishi Eclipse, all non-turbo models. They will fit a 2.0 liter or 420 amp engine as well as an Eagle Talon. This model comes in two pieces with a 2.25-inch outlet and bolts on directly.

The Weapon R race header comes in a 4-2-1 configuration. The Weapon R race head offers a long tube design for the highest RPM flow and staggered tubes for higher torque gains. The Weapon R racing header is suggested for all racing vehicles, but is best for those that have high lift cams or high RPM rev bands. A two and a half inch manifold for the high exhaust flow and the fact that this eliminates the need for the CAT makes it not legal in all 50 states. The Weapon R Race Head was built on years of research and development, including on the dynapack test bench. The Weapon R Race Header is only suggested for off-road use as it is not road legal in the United States at this time, and the Check Engine Light Eliminator is recommended when using these headers. The Weapon R Race Header is available only for the Integra B-series and is listed for around $500, making it the most sought after of all the Weapon R Race Headers.
