Pacemaker 2.5" Performance Exhaust System with 1 7/8" Tuned Headers & Rear Pipe Only for HSV VZ Sedan (6.0L V8) - PP5363-14
Unlock major horsepower gains and unleash an ultra-aggressive muscle roar from your 6.0L Gen IV LS2 engine with the Pacemaker Sport Systems complete performance exhaust solution. Specifically engineered for the HSV VZ Sedan platform, this high-flow setup is configured with a high-volume "Rear Pipe Only" exit plan instead of a standard rear muffler assembly. Featuring large-diameter 1 7/8" primary tuned headers paired with a smooth 2.5" mandrel-bent layout, it delivers maximum exhaust gas velocity while providing an unrestricted bark. It is the ultimate match for cammed, modified, or high-scavenging 6.0L builds that demand peak top-end performance and a standout racetrack sound. Note: Fits HSV VZ Sedan models (2004–2006) equipped with the 6.0L Gen IV LS2 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 HSV platform.
- Complete Headers Setup: Total kit featuring 1 7/8" 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.
- 1 7/8" Tuned Headers: Upgraded large-tube design 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 flow restriction.
- Hanger Integration: Designed as a direct bolt-on layout utilizing the vehicle's factory mounting points.
