Pacemaker Full Twin 2.5" Performance Exhaust System with 1 7/8" 4-into-1 Competition Headers & Hi-Flow Cats for Holden VE & VF Sedan (6.0L & 6.2L V8) - PP5382-01

Unleash maximum top-end horsepower, optimize high-RPM cylinder gas velocity, 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 7/8" 4-into-1 competition extractors. Specifically engineered to satisfy the high-volume gas clearance demands, intense thermal loads, and extraction thresholds of the high-performance Holden 6.0L (L98/L76/L77) and 6.2L (LS3) Gen IV V8 powerplants, this massive primary setup is highly optimized for modified, cammed, or high-revving platforms. This premium full system is precision-molded to trace the sedan floor pan lines, clear standard wheelbase chassis channels, and map perfectly around the multi-link independent rear suspension geometry of the VE and VF series sedan architectures. 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 body resonance to preserve a completely clean, drone-free highway cruising experience.

Note: Fits Holden VE and VF Sedan models (2006 to 2017) equipped with Gen IV 6.0L or 6.2L LS3 V8 engine configurations; does not fit Utility (Ute), Sportwagon, or long-wheelbase Statesman/Caprice platforms due to structural floor pan 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 VE/VF platform.

• Complete Competition Kit: Comprehensive track-and-street performance solution incorporating high-flow 1 7/8" 4-into-1 headers, 3" metallic high-flow catalytic converters, and a full matching twin 2.5-inch performance intermediate-to-rear exhaust layout.
• 4-into-1 Design Architecture: Race-proven competition extractor layout featuring large-bore 1 7/8" primaries running into a merged collector to optimize top-end gas scavenging and unlock significant high-RPM power gains.
• 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 sports 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 Holden VE and VF Sedan models powered by Gen IV 6.0L or 6.2L LS2 / LS3 V8 engine configurations built from July 2006 to October 2017.
• Sedan Specific Routing Geometry: Due to underbody cavity clearances, standard wheelbase dimensions, and unique factory rubber insulation paths matching the sedan rear subframe assembly, this configuration features chassis-specific intermediate plumbing lengths. It will not adapt correctly to Utility (Ute), Sportwagon, or long-wheelbase Statesman/Caprice platforms due to rear assembly differences.
• The large-diameter 1 7/8" 4-into-1 competition header primary pipes are custom-formed for maximum volumetric gas clearance at higher engine revs, making this kit highly ideal for modified, performance-tuned, cammed, or supercharged engine applications.
• Full kit scope: Comprehensive high-flow solution from engine block to rear exit, including 1 7/8" primary competition headers, premium 3" high-flow metallic catalytic converters, twin 2.5" intermediate plumbing paths, and a signature double-skinned rear muffler assembly.
• Direct bolt-on design maps seamlessly onto vehicle-specific factory rubber hanger positions. No custom fabrication or welding mapping 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.
