Meticulously engineered to balance optimal exhaust gas velocity tracking with excellent total volumetric flow, this 1 3\/4\" primary setup serves as the ideal high-efficiency configuration for standard to moderately modified or daily-driven street performance builds. Specifically configured for the long-wheelbase Holden 6.0L and 6.2L Gen IV V8 engine architectures, this premium full system is precision-molded to trace the elongated floor pan lines, clear luxury wheelbase chassis channels, and map perfectly around the multi-link independent rear suspension geometry of the WM and WN series platforms. By upgrading your stock layout to high-flow 4-into-1 headers paired with smooth, mandrel-bent twin 2.5\" plumbing and 3\" high-flow metallic catalytic converters, it maximizes gas velocity tracking to completely eliminate power-robbing backpressure under heavy acceleration. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with 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 long-wheelbase luxury body resonance to preserve a completely clean, drone-free highway cruising experience.\u003c\/p\u003e\n    \u003cp style=\"color: #222222 !important;\"\u003e\u003cem style=\"color: #222222 !important;\"\u003eNote: Fits Holden Statesman and Caprice WM \u0026amp;
