Holden Commodore VT VX VY VZ V8 Pacemaker High Flow Cats CAT5361-100L/R

Pacemaker CAT5361-100L/R High Flow Catalytic Converters are designed for selected Holden Commodore VT, VX, VU, VY and VZ V8 applications fitted with compatible Pacemaker headers, particularly the PH5361 header range.

CAT5361-100L/R uses a 3" (76mm) inlet and 2½" (63mm) outlet with a 100-cell metallic substrate, providing a high-flow catalytic converter solution between compatible Pacemaker headers and a 2½" performance exhaust system.

The supplied product information specifies a concave inlet design intended to increase effective inlet surface area and improve exhaust gas distribution across the catalytic converter substrate.

IMPORTANT – CAT5361-100L/R is the 2½" exhaust-system version. For a 3" exhaust system, see Pacemaker CAT5361-300.

Please check availability, header compatibility and current lead time before ordering.

Construction

Pacemaker CAT5361-100L/R uses a metallic catalytic converter substrate with a 100-cell configuration designed for high-flow performance exhaust applications.

The 3" inlet and 2½" outlet provide the required transition between compatible Pacemaker headers and a 2½" downstream exhaust system.

The supplied product information specifies a concave inlet designed to distribute exhaust gas across the catalytic converter substrate.

Vehicle Fitment

• Make: Holden / HSV
• Models: Commodore / Ute / applicable Statesman, Caprice and HSV variants
• Series: VT / VX / VU / VY / VZ and corresponding WH / WK / WL applications
• Engine: Selected LS-series V8 applications
• Primary Header Application: Pacemaker PH5361
• Exhaust Connection: 2½" performance exhaust system

Important: Fitment is determined by the Pacemaker header and exhaust configuration rather than the vehicle model alone. Confirm the exact header part number and downstream exhaust size before ordering.

CAT5361-100 vs CAT5361-300

Pacemaker offers two catalytic converter configurations for this header family depending on the size of the downstream exhaust system.

CAT5361-100L/R: Designed for connection to a 2½" exhaust system.

CAT5361-300: Designed for connection to a 3" exhaust system.

Confirm the diameter and configuration of the downstream exhaust before selecting the catalytic converters.

Fitment Notes

PH5361: CAT5361-100L/R is a confirmed Pacemaker catalytic converter application for PH5361 headers when used with the appropriate 2½" Pacemaker exhaust configuration.

PH5362: Existing application data also lists CAT5361-100L/R with PH5362. However, PH5362 uses a larger 3½" collector outlet, so the complete header-to-catalytic-converter connection arrangement should be confirmed before ordering.

2½" Exhaust: CAT5361-100L/R is intended for the 2½" downstream exhaust configuration.

3" Exhaust: For a 3" downstream exhaust configuration, see CAT5361-300.

Many VT-VZ V8 vehicles now have modified headers, catalytic converters and exhaust systems. Do not select the catalytic converters solely by vehicle model or engine size.

Professional installation is recommended.

Why High Flow Catalytic Converters Matter

A catalytic converter is an important part of the vehicle's emissions system, but it also creates resistance to exhaust gas flow. In a performance application, sufficient converter flow capacity is important when larger headers and a higher-flowing exhaust system are fitted.

The 100-cell metallic substrate used in CAT5361-100L/R provides a high-flow configuration for performance exhaust applications, while the 3" inlet and 2½" outlet provide the transition between compatible Pacemaker headers and a 2½" exhaust system.

Installation Tips

Before installation, confirm the exact Pacemaker header part number and downstream exhaust diameter.

Inspect oxygen sensors, wiring, exhaust mounts, flanges and sealing surfaces before installation.

If replacing catalytic converters following a previous converter failure, the underlying cause should be identified before installing the replacements. Engine misfire, excessive fuel, oil consumption, overheating and other engine faults can damage a catalytic converter.

Professional installation is recommended.

Warranty & Compliance

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

Catalytic converters and exhaust modifications must comply with applicable Australian state or territory emissions, noise and vehicle modification requirements.

All oxygen sensors and other emissions-control equipment required for the vehicle must remain correctly installed and operational.

FAQ

What headers do CAT5361-100L/R catalytic converters suit?
They are a confirmed Pacemaker catalytic converter application for PH5361 headers with the appropriate 2½" exhaust configuration. Other header applications should be confirmed before ordering.

What size are CAT5361-100L/R?
They have a 3" (76mm) inlet and 2½" (63mm) outlet.

Are these 100-cell catalytic converters?
Yes. The supplied specification identifies CAT5361-100L/R as using a 100-cell metallic substrate.

Do I need CAT5361-100 or CAT5361-300?
Use CAT5361-100L/R for the 2½" exhaust configuration. CAT5361-300 is the corresponding option for a 3" exhaust configuration.

Are both catalytic converters included?
Yes. This listing is for the matched pair consisting of CAT5361-100L left and CAT5361-100R right.

Do these catalytic converters suit PH5362?
Existing application information lists CAT5361-100L/R with PH5362, but because PH5362 has a larger 3½" collector outlet, please confirm the complete connection arrangement with Best Mufflers before ordering.

Can I pick up from the store?
Yes. Pick up is available but must be pre-arranged before collection.
