Holden Commodore VE VF 6.0L 6.2L V8 Pacemaker High Flow Cats CAT5380-100L/R

Pacemaker CAT5380-100L/R High Flow Catalytic Converters are designed for selected Holden Commodore VE-VF and WM-WN Statesman/Caprice models fitted with applicable 6.0L and 6.2L V8 engines and Pacemaker PH5381, PH5382 or PH5387 headers.

CAT5380-100L/R is specifically designed for applications running a 2½" performance exhaust system. The converters transition from the 3" (76mm) outlet of the Pacemaker headers to a 2½" (63mm) exhaust connection.

Featuring a 100-cell metallic substrate, these high-flow catalytic converters are designed to reduce exhaust restriction compared with a more restrictive converter while retaining a catalytic converter in the exhaust system.

IMPORTANT – CAT5380-100L/R is the 2½" exhaust-system version. For a 3" exhaust system, use Pacemaker CAT5387-100L/R.

Please check availability and current lead time before ordering.

Construction

Pacemaker CAT5380-100L/R uses a metallic catalytic converter substrate designed for high-flow performance applications.

The converter configuration provides the transition from the 76mm (3") outlet of the compatible Pacemaker headers to a 63mm (2½") downstream exhaust connection.

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

Vehicle Fitment

CAT5380-100 vs CAT5387-100

Pacemaker offers two high-flow catalytic converter configurations for PH5381, PH5382 and PH5387 headers depending on the diameter of the downstream exhaust system.

CAT5380-100L/R: Designed for a 2½" exhaust system.

CAT5387-100L/R: Designed for a 3" exhaust system.

Both are used downstream of Pacemaker headers with 3" collector outlets, but the correct catalytic converter must be selected to match the exhaust system being fitted.

Fitment Notes

Confirm Exhaust Size: CAT5380-100L/R should be selected when the vehicle is being fitted with a 2½" performance exhaust system.

3" Exhaust: If the vehicle has or is being fitted with a 3" exhaust system, use Pacemaker CAT5387-100L/R instead.

Header Compatibility: Pacemaker currently lists CAT5380-100L/R as a high-flow catalytic converter option for PH5381, PH5382 and PH5387.

Because many VE and VF V8 vehicles have modified exhaust systems, always confirm the existing header and downstream exhaust configuration before ordering.

Professional installation is recommended.

What's Included

• 1 x Pacemaker CAT5380-100L left-side catalytic converter assembly
• 1 x Pacemaker CAT5380-100R right-side catalytic converter assembly

Gaskets, bolts and other installation hardware should not be assumed to be included unless specifically confirmed with the current kit before ordering.

Recommended With

• Pacemaker PH5381 4-into-1 Competition Headers
• Pacemaker PH5382 4-into-1 Competition Headers
• Pacemaker PH5387 Tri-Y Headers
• Pacemaker 2½" performance exhaust system

Why High Flow Catalytic Converters Matter

A catalytic converter forms an important part of the exhaust system but also presents a potential restriction to exhaust gas flow. In a performance application, the converter needs sufficient flow capacity to work effectively with the larger headers and exhaust system.

The 100-cell metallic substrate used in CAT5380-100L/R provides a high-flow configuration designed for performance exhaust applications, while the 3" inlet and 2½" outlet provide the required transition between compatible Pacemaker headers and a 2½" exhaust system.

Warranty & Compliance

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

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

Where a vehicle is required to retain functioning catalytic converters and other emissions-control equipment, those components must remain correctly installed and operational.
