Pacemaker 3" Performance Exhaust System with 1-3/4" Headers for Holden Statesman Caprice WM WN 6.0L 6.2L V8 2006–2017 - PP5381-66

Pacemaker Full 3" Performance Exhaust System with 1 3/4" 4-into-1 Tuned Headers & Hi-Flow Cats for Holden Statesman & Caprice WM / WN (6.0L & 6.2L V8) - PP5381-66

Unleash significant torque fields, optimize mid-to-high RPM cylinder scavenging, and deliver an aggressive, deep Australian V8 muscle note from your small-block engine with the Pacemaker Sport Systems complete large-bore 3-inch performance exhaust solution featuring 1 3/4" 4-into-1 tuned primary extractors. Meticulously engineered to balance optimal exhaust gas velocity tracking with massive total volumetric flow, this 1 3/4" primary setup serves as the ideal high-efficiency configuration for standard to moderately modified or daily-driven street performance builds. Specifically configured for the long-wheelbase Holden 6.0L and 6.2L Gen IV V8 engine architectures, this premium full system is precision-molded to trace the elongated floor pan lines, clear luxury wheelbase chassis channels, and map perfectly around the multi-link independent rear suspension geometry of the WM and WN series platforms. By upgrading your stock layout to high-flow 4-into-1 headers paired with smooth, mandrel-bent 3" plumbing and 3" high-flow metallic catalytic converters, it maximizes gas velocity tracking to completely eliminate power-robbing backpressure under heavy acceleration. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with patented V-Tex technology and signature double-skinned mufflers, producing an authoritative performance roar on throttle while actively engineering out harsh interior cabin boom or long-wheelbase luxury body resonance to preserve a completely clean, drone-free highway cruising experience.

Note: Fits Holden Statesman and Caprice WM & WN models (August 2006 to October 2017) including Series I and Series II configurations equipped with 6.0L or 6.2L V8 engines; does not fit short-wheelbase Commodore (VE/VF) Sedan, Sportwagon, or Utility variants due to structural length and rear routing path differences.

Features:

Precision-manufactured in Australia to deliver a high-velocity flow upgrade, maximum structural longevity under intense heat, and a refined performance acoustic profile for the premium Holden long-wheelbase platform.

• Complete Performance Kit: Comprehensive track-and-street performance solution incorporating high-flow 1 3/4" 4-into-1 headers, 3" metallic high-flow catalytic converters, and a full matching large-bore 3-inch performance intermediate-to-rear exhaust layout.
• 1 3/4" 4-into-1 Design Architecture: Tuned extractor layout featuring high-velocity 1 3/4" primaries running into a merged collector to optimize mid-range torque retention and unlock seamless high-RPM power gains on street-driven applications.
• Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue under extreme loads.
• Mandrel Bent Tubing: Rigid high-flow 3" (76.2mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and prevent restriction.
• V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of large-bore V8 layouts without creating any power-robbing flow restrictions.
• Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case reinforcement, preventing case distortion and internal packing blowout under heavy thermal load constraints.
• Direct Bolt-On Layout: Engineered as a comprehensive, vehicle-specific full bolt-up kit that mounts directly onto existing factory rubber hanger positions—no custom fabrication required.

Vehicle Applications:

Important Fitment Notes:

• Specifically engineered to fit long-wheelbase Holden Statesman and Caprice WM & WN variants built from August 2006 to October 2017 (Series I and Series II models).
• Long-Wheelbase Routing Geometry: Due to extended vehicle specifications, custom underbody layout cavities, and alternative structural lengths designed precisely to clear premium chassis rails, this layout features distinct intermediate tubing path extensions. It will not adapt to standard wheelbase Sedan (VE/VF), Sportwagon, or Utility (Ute) options.
• The 1 3/4" tuned primary header tubes are custom-formed to step up engine torque fields and lower-end exhaust velocity response metrics, establishing this kit as an exceptionally premium alternative for high-performance daily drivers and street cars.
• Full kit scope: Comprehensive high-efficiency performance solution from engine block to rear exit, including 1 3/4" primary headers, premium 3" high-flow metallic catalytic converters, large-bore 3" intermediate plumbing paths, and a signature double-skinned rear muffler assembly.
• Direct bolt-up architecture interfaces seamlessly with original vehicle-specific rubber hanger brackets. No custom modification or cutting layout mapping is required.
• Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, check tight steering column tolerances, and secure gas-tight seals under the floor pan.
