Pacemaker 2.5" Performance Exhaust System with 1 7/8" Tuned Headers & Rear Pipe Only for Holden VY Series 2 & VZ Sedan (5.7L V8)
Unlock major horsepower gains and unleash an ultra-aggressive muscle roar from your 5.7L LS1 engine with the Pacemaker Sport Systems complete performance exhaust solution. Specifically engineered for the Holden VY Series 2 and VZ Sedan platforms, this heavy-breathing configuration replaces the standard rear tail muffler assembly with a high-volume "Rear Pipe Only" section. Featuring large-diameter 1 7/8" primary tuned headers paired with a smooth 2.5" mandrel-bent line, it delivers maximum exhaust gas velocity while providing an unrestricted racetrack bark. It is the ultimate match for cammed, modified, or high-scavenging 5.7L builds that demand peak performance and an intense sound profile. Note: Fits Holden VY Series 2 and VZ Sedan models (2003–2006) equipped with the 5.7L LS1 V8 engine.
Features:
Precision-manufactured in Australia to deliver the absolute peak in flow efficiency, heavy-duty scavenging, and raw acoustic output for the high-performance Commodore sedan platform.
- Complete Headers Setup: Total kit featuring large primary tuned headers, 3" hi-flow cats, and active piping sections.
- Rear Pipe Configuration: Built with a straight-through rear pipe replacing the standard tail muffler for maximum exhaust bark and unrestricted flow potential.
- 1 7/8" Tuned Headers: Upgraded large-tube extractor layout engineered to optimize top-end power potential and high-RPM volumetric efficiency.
- Premium Materials: Constructed completely from durable Exhaust Grade 409 Stainless Steel for superior longevity under high thermal stress.
- Mandrel Bent Tubing: Heavy-duty 2.5" (63.5mm) pipe structure ensures a smooth, constant internal diameter to prevent backpressure.
- Hi-Flow Cats: Supplied with 3" premium high-flow metallic catalytic converters transitioning cleanly to a high-velocity 2.5" path.
