Pacemaker Full 3" Performance Exhaust System with 1 7/8" 4-into-1 Competition Headers & Hi-Flow Cats for HSV VE E-Series E1 Sedan (6.0L Gen IV LS2 V8) - PP5382-52

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 large-bore 3-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 6.0L Gen IV LS2 V8 engine configuration, this massive primary setup is 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 early VE series HSV architecture. By upgrading your stock layout to high-flow competition 4-into-1 headers paired with smooth, mandrel-bent 3" plumbing and 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 sedan body resonance to preserve a completely clean, drone-free highway cruising experience.

Note: Fits HSV VE E-Series E1 Sedan variants built from September 2006 to August 2009 equipped with the 6.0L Gen IV LS2 V8 engine layout; does not fit Utility (Ute), Sportwagon, or long-wheelbase Grange 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 VE sedan 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 large-bore 3-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 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.
