Fitment Notes

What's Included

• Wildcat WILD276A header / extractor assemblies
• Outlet connection components as supplied

Recommended With

• New exhaust manifold/header gaskets
• High-temperature exhaust gasket sealant
• Replacement manifold studs and nuts where required
• Suitable 2.50" exhaust components for completing the installation

Installation Tips

• Lubricate manifold studs, nuts and exhaust fasteners with WD-40 or a similar penetrating lubricant before removal.
• Remove all traces of the old manifold gaskets before installing the headers.
• Inspect cylinder-head sealing surfaces, manifold studs and threads before installation.
• Trial-fit the headers before completing the downstream exhaust fabrication.
• Check clearance around the automatic transmission, steering, suspension, starter motor and bodywork.
• Protect the painted header surfaces during installation.
• Re-tighten the header/manifold bolts after approximately 500km to help maintain a reliable gasket seal.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 3.4L 5VZ-FE V6 processes a substantial volume of intake air and hot exhaust gas. A well-designed header and exhaust system helps reduce unnecessary restriction and improve exhaust scavenging, torque, throttle response and usable engine performance.
