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) - Rear Pipe Only Layout - PP5367-32

Unleash devastating low-to-mid range torque, optimize scavenging velocity tracking, and extract a raw, track-inspired muscle car bark from your 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 an aggressive, straight-through rear section design. 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. This track-biased version features a specialized 'Rear Pipe Only' layout configuration that deletes standard rear restrictive mufflers, completely opening up your vehicle's external sound fields. As Australia’s premium exhaust innovator, Pacemaker combines this heavy-hitting flow with 3" metallic high-flow catalytic converters and heavy-duty Tri-Y primary runs, generating an uncompromising acoustic statement when accelerating while ensuring straightforward, direct bolt-up compatibility underneath your performance wagon platform.

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 raw, track-biased performance acoustic profile.

• Complete Performance Kit: Comprehensive track performance upgrade incorporating premium tuned Tri-Y headers, 3" high-flow metallic catalytic converters, and a matching full 2.5-inch performance intermediate-to-rear layout path.
• 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.
• Rear Pipe Only Configuration: Stripped-back straight tailpipe construction deletes the rear mufflers to maximize volumetric gas velocity while establishing an exceptionally loud, crisp, uncompromised V8 acoustic bark.
• 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.
• 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.
• Acoustic Profile Note: This specialized setup features a straight-through rear pipe configuration with no rear acoustic muffler boxes. It will generate an exceptionally aggressive, highly pronounced V8 racing tone that is significantly louder than muffled sports applications.
• 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.
