Pacemaker Full Twin 2.5" Performance Exhaust System with 1 3/4" 4-into-1 Tuned Headers & Hi-Flow Cats for Holden VE & VF Utility (6.0L & 6.2L V8) - PP5381-17

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 twin 2.5-inch performance exhaust solution featuring 1 3/4" 4-into-1 tuned primary extractors. Meticulously engineered to balance optimal exhaust gas velocity tracking with excellent 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 high-performance Holden 6.0L and 6.2L Gen IV V8 engine architectures, this premium full system is precision-molded to trace the utility floor pan lines, flat cargo load beds, and rear suspension layouts unique to the VE and VF commercial performance architecture. By upgrading your stock layout to high-flow competition 4-into-1 headers paired with smooth, mandrel-bent twin 2.5" 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 open cargo tray resonance to preserve a completely clean, drone-free highway cruising experience.

Note: Fits Holden VE and VF Utility (Ute) models built from August 2007 to October 2017 equipped with Gen IV 6.0L or 6.2L LS3 V8 engine configurations; does not fit Sedan, Sportwagon, or long-wheelbase Statesman/Caprice platforms due to structural chassis routing, intermediate pipe lengths, and rear assembly 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 iconic Holden V8 utility 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 twin 2.5-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.
• Utility Specific Clearance: Custom-tailored plumbing path configured to route cleanly beneath flat cargo bed structures, drop-sides, and vehicle-specific commercial chassis lines.
• 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 twin 2.5" (63.5mm) 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 open utility cabs 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 Holden Commodore VE and VF Ute models powered by Gen IV 6.0L or 6.2L LS3 V8 engine configurations built from August 2007 to October 2017.
• Utility Specific Routing Geometry: Due to underbody chassis cavity variations, extended layout specifications, and alternative rear hanger brackets intended to clear tray architectures, this layout features distinct intermediate lengths. It will not adapt correctly to Sedan, Sportwagon, or long-wheelbase Statesman/Caprice platforms.
• 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, twin 2.5" 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.
