Pacemaker Twin 2.5" Performance Exhaust System with Tri-Y Headers for HSV VF 6.2L V8 Sedan & Sportwagon 2013–2017 - PP5387-05

Pacemaker Full Twin 2.5" Performance Exhaust System with Tri-Y Headers for HSV VF Sedan & Sportwagon (6.2L LS3 V8) - PP5387-05

Maximize street exhaust gas velocity, optimize low-to-mid range engine cylinder scavenging, and unleash a crisp, deep Australian V8 muscle note from your high-performance Gen IV powerplant with the Pacemaker Sport Systems complete twin 2.5-inch performance exhaust solution featuring premium Tri-Y headers. Specifically engineered to maximize cylinder scavenging and satisfy the high-velocity gas volume of elite HSV Gen IV 6.2L LS3 V8 engines, this high-flow system is precision-molded to clear the standard floor pan lines, chassis layout, and multi-link rear suspension geometry of the VF series HSV sedan and wagon architecture. By pairing race-proven, high-scavenging Tri-Y primary extractors with smooth, mandrel-bent heavy-duty twin 2.5-inch plumbing and a premium high-flow cat section, it completely eradicates power-robbing backpressure under wide-open throttle. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with patented V-Tex technology and signature double-skinned mufflers, delivering a thumping muscle car rumble outside while actively engineering out harsh interior cabin boom or highway drone to preserve a clean, drone-free performance drive. Note: Fits HSV VF Sedan and Sportwagon models (2013–2017) equipped with Gen IV 6.2L LS3 V8 engine configurations; does not fit Utility (Ute) or long-wheelbase Grange variants without structural rear-section modification.

Features:

Precision-manufactured in Australia to deliver a premium high-velocity flow upgrade, maximum structural longevity under intense heat, and an uncompromised performance acoustic profile for the iconic HSV VF platform.

• Complete Headers & Full System: Comprehensive track-and-street performance solution incorporating high-scavenging Tri-Y primary headers, 3" metallic high-flow catalytic converters, and a full matching twin 2.5-inch performance intermediate-to-rear exhaust layout.
• Tri-Y Design Architecture: Advanced multi-secondary extractor design engineered explicitly to optimize cylinder scavenging efficiency and boost low-to-mid range torque retention.
• Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue.
• 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 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 load.
• 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 VF Sedan and Sportwagon models powered by Gen IV 6.2L V8 LS3 engine configurations (2013–2017).
• Sedan & Wagon Specific Chassis Layout: This configuration features tailor-formed exhaust pipe paths, bracket placements, and specific routing paths designed precisely to mount cleanly under standard sedan and wagon floor pan contours. It will not adapt correctly to Utility (Ute) or long-wheelbase Grange platforms without structural rear-section modification.
• Full kit scope: Comprehensive high-flow solution from engine block to rear exit, including performance Tri-Y headers, premium 3" high-flow metallic catalytic converters, twin 2.5" intermediate plumbing, 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, strict engine bay alignment, and gas-tight seals under the floor pan.
