Pacemaker Twin 2.5" Performance Exhaust System with 1-3/4" Tri-Y Headers for HSV VE E-Series E2 6.0L LS2 V8 Sedan 2009–2010 - PP5387-03

Pacemaker Full Twin 2.5" Performance Exhaust System with 1 3/4" Tri-Y Headers & Hi-Flow Cats for HSV VE E-Series E2 Sedan (6.0L Gen IV LS2 V8) - PP5387-03

Maximize street exhaust gas velocity, optimize low-to-mid range engine cylinder scavenging, and unleash a crisp, deep Australian V8 muscle tone from your small-block powerplant with the Pacemaker Sport Systems complete twin 2.5-inch performance exhaust solution featuring high-efficiency 1 3/4" Tri-Y headers. Custom-engineered specifically to handle the extraction demands, thermal stress, and heat generation of the high-performance 6.0L Gen IV LS2 V8 engine configuration, this premium full system is precisely shaped to map the sedan floor pan lines, standard wheelbase layout, and multi-link independent rear suspension paths of the VE series HSV chassis architecture. By pairing race-proven 1 3/4" primary extractor pipes with smooth, mandrel-bent twin 2.5" plumbing and premium 3" high-flow metallic catalytic converters, it rapidly clears spent gases to completely eradicate 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, delivering a commanding, throaty performance bark on throttle while actively engineering out harsh, intrusive interior cabin boom or highway drone at cruising speeds. Note: Fits HSV VE E-Series E2 Sedan variants built from September 2009 to August 2010 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 high thermal stress, and a refined performance acoustic profile for the iconic VE sedan platform.

• Complete Extractors & Full System: Comprehensive street-and-track performance solution incorporating 1 3/4" primary Tri-Y headers, 3" metallic high-flow catalytic converters, and a full matching twin 2.5-inch performance cat-back system.
• Tri-Y Design Architecture: Advanced multi-secondary extractor design engineered explicitly to optimize scavenging efficiency and boost low-to-mid range torque response on small-block V8 configurations.
• Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior resistance to thermal fatigue and rust.
• 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 backpressure.
• V-Tex Technology: Advanced internal patented anti-drone configuration cancels out harsh, low-frequency cabin resonance typical of sedan cabins without restricting gas velocity.
• Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium case reinforcement, preventing case distortion and internal packing blowout under heavy 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.

Important Fitment Notes:

• Specifically engineered to fit HSV VE E-Series E2 Sedan variants powered by the 6.0L Gen IV LS2 V8 engine build date path (September 2009 to August 2010 builds).
• 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 / Maloo), Sportwagon, or long-wheelbase Grange platforms.
• Full kit scope: Comprehensive high-efficiency performance solution from engine block to rear exit, including 1 3/4" primary Tri-Y 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, strict engine bay steering line alignment, and gas-tight seals under the floor pan.
