Long Tube Stepped Exhaust Manifold

These headers are designed with advanced computer-aided design and flow testing to ensure optimal efficiency. Key features include long primary tubes for enhanced high-RPM power and stepped sizing to optimize torque output across a wider RPM range. The race merge collector provides ample exhaust flow for maximum performance gains, while the catalytic converter-free design maximizes power output and reduces back pressure. Constructed from lightweight stainless steel, these headers also contribute to weight reduction for improved handling. These race headers are ideal for racing applications such as drag racing and road racing, as well as high-performance builds and vehicles equipped with modifications like camshafts and high-flow intakes. Drivers who enjoy pushing their engines to their limits will appreciate the increased power and responsiveness, along with an enhanced, more aggressive exhaust sound. This header is recommended for the 2004-2006 Ford Focus 2.0L. Professional installation is recommended. A CEL (Check Engine Light) Eliminator is also recommended for this header and is available separately (Part# 963-111-101 or Upgraded Adjustable Part# 963-111-104). Please note that this header eliminates the catalytic converter and is NOT 50 State legal; it is for OFF-ROAD USE ONLY and not legal for use on public highways.
