Nissan Patrol Y62 5.6L V8 Pacemaker High Flow Catalytic Converters CAT9580-100L/R

Pacemaker CAT9580-100L and CAT9580-100R high-flow catalytic converter assemblies are designed for the Nissan Patrol Y62 5.6L V8 when installing Pacemaker PH9580 Tri-Y headers.

The CAT9580-100 assemblies are used in Pacemaker's complete Y62 performance exhaust packages and provide the dedicated left- and right-hand catalytic converter connections between the PH9580 headers and the downstream performance exhaust system.

Pacemaker describes these as high-flow catalytic converters developed to reduce exhaust restriction, allowing the PH9580 header and performance exhaust package to operate efficiently while retaining catalytic converters.

IMPORTANT – Series 1-3 and Series 4-5 use different sensor wiring extensions. Confirm your Y62 series before ordering.

Please check availability and current lead time before ordering.

Why High-Flow Catalytic Converters Matter

At 4,000 rpm, the 5.6L V8 theoretically draws approximately 11,200 litres of intake air per minute at 100% volumetric efficiency and expels around 33,600 litres of hot exhaust gas per minute at approximately 600°C.

Actual airflow varies with RPM, engine load, volumetric efficiency, induction system, camshaft timing and engine tune. These figures are theoretical values intended to illustrate the substantial volume of gas that must pass through the exhaust system.

A restrictive catalytic converter can become a significant restriction in a high-flow exhaust system. Pacemaker's high-flow catalytic converters are designed to reduce restriction while retaining catalytic converters as part of the PH9580 performance exhaust package.

Installation Tips

Ensure the engine is operating correctly before installing replacement catalytic converters. Engine misfire, excessive fuel delivery, oil consumption or other engine-management faults can cause excessive converter temperatures and premature catalytic converter failure.

Confirm the correct sensor extension components for the vehicle series before installation and ensure all oxygen and heat sensors are correctly connected and positioned.

Professional installation is recommended, particularly when fitting the converters together with PH9580 headers.

Warranty & Compliance

Pacemaker catalytic converters are covered against manufacturing defects subject to Pacemaker's current warranty terms and conditions.

Catalytic converters and associated oxygen sensors form part of the vehicle's emissions-control system. Installation must comply with applicable state or territory emissions, roadworthiness and vehicle modification requirements.

FAQ

What vehicle do CAT9580-100L/R catalytic converters suit?
They are designed for the Nissan Patrol Y62 5.6L V8 when used with Pacemaker PH9580 headers.

Are CAT9580-100L and CAT9580-100R different?
Yes. Pacemaker specifies separate left-hand and right-hand catalytic converter assemblies.

Do they suit PH9580 headers?
Yes. CAT9580-100L/R are the catalytic converter assemblies Pacemaker uses in its complete PH9580 Y62 header packages.

What O2 sensor extensions do Series 1-3 use?
