1-Pc 4-2-1 Stainless Steel Race Header (953-117-103) by Weapon-R®. These free-flowing headers are designed to increase exhaust flow and make as much horsepower and torque as possible.

Weapon-R Catalog

Features:

  • Maximizes engine performance
  • Designed to work without the catalytic Converter
  • Made from 304 Stainless Steel
  • CNC machined flanges
  • Highly polished finish

No engine needs as much air flow as a racing engine. They operate at high rpm and need components that create as much air/fuel flow as possible into the combustion chamber. But no matter how well the intake side breathes the engine will be strangled if there isn’t an effective means of getting rid of the spent exhaust gases. An efficient exhaust header not only creates a pathway for the exhaust, it also optimizes the engine power band and peak power point.

Weapon-R’s Race headers are ideal for high rpm racing engines. They’re designed with long primary tubes for high rpm power and stepped size tubing for higher torque gains. They work best with high lift cams that create power at high rpm. And they’re not intended for use with the catalytic converter.

Each Race Header is specifically designed for the application and made from 304 Stainless Steel for durability. The tubes are CNC mandrel-bent to specification. The flanges are CNC machined and welded inside and out to prevent leaks and cracking. Then the whole assembly is polished to a high gloss.

Weapon-R® makes high quality performance parts, at affordable prices, for sport compact cars. All products are carefully designed using the latest computer simulation and modeling techniques, followed by extensive dyno testing. Finally, all parts are rigorously street and race tested to make sure they’ll perform flawlessly in your car. Weapon-R draws on over a decade’s experience, involvement in various forms of motor sports, and their commitment to research and development, to bring you the highest quality and best value performance parts in the industry.
