Pacemaker Full 2.5" Performance Exhaust System with Tri-Y Headers & Hi-Flow Cats for Holden VY Series 2 & VZ Station Wagon (5.7L Gen III V8) - Rear Pipe Only Layout - PP5367-33

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 5.7L Gen III V8 station wagon architectures, 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 VY Series 2 and VZ Station Wagon variants built from August 2003 onwards equipped with the 5.7L Gen III V8 engine layout; does not fit Sedan, Utility (Ute), One Tonner, or later generation VE/VF 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.

Important Fitment Notes:

  • Specifically engineered to fit Holden Commodore VY Series 2 and VZ Station Wagon configurations powered by the 5.7L Gen III V8 engine layout.
  • Wagon Specific Geometry: Designed strictly to conform around traditional VY/VZ 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 VE/VF wagon 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.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.
