Pacemaker 2.5" Exhaust System with Tri-Y Headers for Holden WM WN Statesman Caprice V8 2006–2017 - PP5387-06

Pacemaker Full 2.5" Performance Exhaust System with Tri-Y Headers for Holden WM & WN Statesman / Caprice (6.0L & 6.2L V8) - PP5387-06

Extract maximum low-to-mid range torque and unlock an authoritative, deep muscle car roar from your Gen IV or Gen V small-block with the Pacemaker Sport Systems complete 2.5" performance exhaust solution featuring premium Tri-Y headers. Specifically engineered to maximize cylinder scavenging and satisfy the high-velocity exhaust tracking demands of the Holden 6.0L (L98/L76/L77) and 6.2L (LS3) V8 powerplants, this high-flow system is precision-molded to clear the long-wheelbase floor pan lines and independent rear suspension geometry characteristic of the luxury flagship luxury cruiser platform. By pairing race-proven high-scavenging Tri-Y extractors with smooth, mandrel-bent heavy-duty 2.5-inch plumbing and a premium high-flow cat section, it completely eradicates power-robbing backpressure under acceleration. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with patented V-Tex technology and signature double-skinned mufflers, delivering a commanding rumble outside while actively engineering out harsh interior cabin boom or high-load highway drone to preserve the signature refined interior comfort of the long-wheelbase luxury cabin. Note: Fits Holden WM and WN Series Statesman and Caprice long-wheelbase models (2006–2017) equipped with Gen IV / Gen V 6.0L or 6.2L V8 engine configurations; does not fit standard short-wheelbase VE/VF Sedan variants without mid-section modification.

Features:

Precision-manufactured in Australia to deliver a premium high-velocity flow upgrade, maximum structural longevity under intense heat, and an elite performance acoustic profile for the iconic luxury long-wheelbase V8 platform.

• Complete Headers & System Kit: Comprehensive track-and-street performance solution incorporating high-scavenging Tri-Y primary headers, premium high-flow metallic catalytic converter sections, and a full matching 2.5" performance cat-back layout.
• Tri-Y Design Architecture: Advanced multi-secondary extractor design engineered explicitly to optimize scavenging efficiency and boost low-to-mid range torque retention.
• Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue.
• Mandrel Bent Tubing: Rigid high-flow pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and backpressure.
• V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of large-bore v8 layouts without restricting gas velocity.
• Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case protection, completely preventing internal acoustic packing blowout under intense thermal stress.
• Direct Bolt-On Layout: Engineered as a comprehensive, vehicle-specific full bolt-up kit that mounts directly onto existing long-wheelbase factory hanger positions—no custom fabrication required.

Important Fitment Notes:

• Specifically engineered to fit Holden WM and WN Series Statesman and Caprice models powered by the 6.0L or 6.2L V8 engine configuration (2006–2017).
• Long-Wheelbase Specific Chassis Layout: Due to the longer center floor pan contours, extended wheelbase path, and unique rear luxury hanger orientation characteristic of the Statesman and Caprice platforms, this configuration features vehicle-specific intermediate plumbing lengths. It will not adapt cleanly to short-wheelbase VE or VF Sedan models without extension adjustment.
• Full kit scope: Comprehensive high-flow solution from block to tips, including performance Tri-Y headers, premium 3" high-flow metallic converters, intermediate sections, and signature double-skinned rear mufflers for complete acoustic management.
• Direct bolt-on design reuses your long-wheelbase factory hanger lines. No custom cutting layout or welding mapping required.
• Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, clean engine bay fitment, and gas-tight seals under the floor pan.
