Suzuki Sierra SJ410 1.0L F10A Headers 1980–1985 – Wildcat WILD007

Wildcat WILD007 exhaust headers (extractors) are designed for selected Suzuki Sierra SJ410 models from 1980–1985 fitted with the 1.0L F10A petrol engine. WILD007 is also listed for selected Spanish-built Santana RHD models from 1985–1988.

Featuring an interference-style header design, WILD007 uses 1.50" primary pipes, 1.58" secondary pipes and a 1.75" outlet. This combination is designed to improve exhaust gas flow and scavenging while maintaining good exhaust velocity, helping improve usable torque, throttle response and engine performance.

The headers replace the original exhaust manifold; however, WILD007 is a cut-and-weld application. The downstream exhaust must be cut and fabricated to connect correctly to the new header outlet. Professional installation by an experienced exhaust workshop is recommended.

Please check availability and current lead time before ordering.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 1.0L F10A petrol engine theoretically draws in approximately 2,000 litres of intake air per minute and can expel around 6,000 litres of hot exhaust gas per minute at approximately 600°C.

A well-designed header and exhaust system helps manage this gas flow efficiently, reducing restriction and improving exhaust scavenging, torque, throttle response and engine performance.

Installation Tips

• Apply penetrating lubricant such as WD-40 or similar to the manifold studs, nuts and exhaust fasteners before removal
• Remove all traces of the old manifold gasket before installing the header
• Inspect the cylinder-head sealing surface, manifold studs and threads before installation
• Fit a new exhaust manifold/header gasket
• Trial-fit and correctly position the header before cutting the existing exhaust system
• Fabricate and weld the downstream exhaust connection only after correct header position and clearance have been confirmed
• Check clearance around the steering, suspension, transmission, starter motor, chassis and bodywork
• Protect the painted header surfaces during trial fitting and installation
• Check the completed exhaust system for leaks after installation
• Inspect and re-tighten the header mounting hardware after approximately 500km to help maintain a reliable gasket seal

Warranty & Compliance

Wildcat headers are covered by the applicable 2-year manufacturer's warranty subject to standard warranty terms and conditions.

Correct installation and adequate clearance around the steering, suspension, chassis and surrounding components are essential. Engine conversions and other vehicle or exhaust modifications may affect fitment.
