Pacemaker 2.5" Performance Exhaust System with Tri-Y Headers for Holden VT VX VY Series 1 5.7L V8 Wagon - PP5367-31

Pacemaker Full 2.5" Performance Exhaust System with Tri-Y Headers & Hi-Flow Cats for Holden VT, VX & VY Series 1 Station Wagon (5.7L Gen III V8) - PP5367-31

Unleash devastating low-to-mid range torque, optimize scavenging velocity tracking, and extract a rich, deep Australian muscle car roar from your high-performance engine block with the Pacemaker Sport Systems full 2.5-inch performance exhaust solution featuring high-efficiency Tri-Y tuned extractors. Specifically configured to maximize power curves on Holden Gen III 5.7L V8 station wagon architectures (LS1 powerplants), this premium package pairs race-bred performance hardware with a fully muffled intermediate and rear system. Custom-molded specifically to match the station wagon floor pan lines, clear elongated family wheelbase chassis structures, and map perfectly around vehicle-specific rear cargo floor structures, it completely eliminates power-robbing backpressure under wide-open throttle transitions. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with 3" metallic high-flow catalytic converters, 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 station wagon body resonance to preserve a completely clean, drone-free cruising experience.

Note: Fits Holden VT, VX, and VY Series 1 Station Wagon variants powered by the 5.7L Gen III V8 engine layout; does not fit Sedan, Utility (Ute), One Tonner, or later generation platforms due to significant chassis length, structural floor contour, and hanger position variations.

Features:

Precision-manufactured in Australia to deliver a heavy-duty high-flow upgrade, exceptional structural longevity under intense heat, and a refined performance acoustic profile for the classic long-wheelbase wagon layout.

• Complete Performance Kit: Comprehensive track-and-street performance upgrade incorporating premium tuned Tri-Y headers, 3" high-flow metallic catalytic converters, and a matching full 2.5-inch intermediate piping route with high-efficiency mufflers.
• Tuned Tri-Y Design Architecture: Secondary-paired pipe layout engineered specifically to build exceptional low-to-mid range torque response, making it the perfect upgrade for heavy family wagon chassis acceleration tracking.
• Wagon Specific Clearance: Custom-tailored plumbing path configured to route cleanly beneath elongated wagon floor contours, deep rear cargo bays, and vehicle-specific station wagon 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.
• High-Flow Mandrel Bent Tubing: Rigid full 2.5" (63.5mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and prevent flow restriction.
• V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of open wagon body structures without restricting gas velocity footprints.
• 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 VT, VX, and VY Series 1 Station Wagon configurations powered by the 5.7L Gen III V8 engine layout.
• Wagon Specific Routing Geometry: Designed strictly to conform around traditional VT/VX/VY wagon floor pan paths, rear floor load areas, and specific rear chassis hanger anchors. It will not adapt to Sedan, Utility (Ute), One Tonner, or later generation platforms due to major structural blueprint layout and length differences.
• Full kit scope: Comprehensive high-efficiency performance solution from engine block to rear exit, including tuned Tri-Y headers, premium 3" high-flow metallic catalytic converters, 2.5" intermediate plumbing paths, and a signature double-skinned rear muffler assembly.
• Direct full 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 steering column tolerances, verify proper pipe routing, and ensure completely gas-tight structural seals under the floor pan.
