Pacemaker Full 3" Performance Exhaust System with Tri-Y Headers for Holden WM & WN Statesman / Caprice (6.0L & 6.2L V8) - PP5387-56

Extract maximum low-to-mid range torque, optimize gas velocity tracking, and unlock an authoritative, deep muscle car rumble from your high-performance Gen IV small-block with the Pacemaker Sport Systems complete large-bore 3" performance exhaust solution featuring premium Tri-Y headers. Custom-engineered specifically to handle the massive scavenging requirements, high thermal thresholds, and heavy gas volume of the heavy-hitting 6.0L (L98/L76/L77) and 6.2L (LS3) V8 powerplants, this premium setup is precision-molded to match the extended floor pan lines, stretched long-wheelbase profiles, and under-car clearance channels unique to the luxury flagship sedan chassis. By pairing race-proven, high-scavenging Tri-Y primary extractors with smooth, mandrel-bent heavy-duty 3-inch plumbing and a premium high-flow cat section, it completely eradicates power-robbing backpressure under wide-open throttle. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with patented V-Tex technology and signature double-skinned mufflers, delivering a thumping performance bark outside while actively engineering out harsh interior cabin boom or executive cabin drone to preserve a completely refined cruising experience. Note: Fits Holden WM and WN Statesman / Caprice models (2006–2017) equipped with Gen IV 6.0L or 6.2L V8 engine configurations; engineered exclusively to suit long-wheelbase (LWB) platforms and will not fit short-wheelbase Sedan, Sportwagon, or Ute variants.

Features:

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

• Complete Headers & Full System: Comprehensive track-and-street performance solution incorporating high-scavenging Tri-Y primary headers, 3" metallic high-flow catalytic converters, and a full matching 3-inch performance intermediate-to-rear long-wheelbase exhaust layout.
• Tri-Y Design Architecture: Advanced multi-secondary extractor design engineered explicitly to optimize cylinder scavenging efficiency and boost low-to-mid range torque retention.
• Long-Wheelbase Specific Geometry: Custom-extended plumbing mapping configured to line up flawlessly with the longer chassis dimensions and specific hanger points of Holden luxury flagships.
• 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 3" (76.2mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and prevent restriction.
• V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of large-bore V8 layouts without creating any power-robbing flow restrictions.
• Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case reinforcement, preventing case distortion and internal packing blowout under heavy load.
• 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 WM and WN Statesman / Caprice luxury models powered by Gen IV 6.0L or 6.2L V8 engine configurations (2006–2017).
• Long-Wheelbase Layout Constraints: Statesman and Caprice models feature a stretched floor pan extension compared to standard sedans. This kit features specific piping extension segments and modified routing geometries tailored explicitly to mount cleanly without modification over luxury-spec subframes. It will not align properly with standard short-wheelbase VE/VF Sedan, Sportwagon, or Ute variants.
• Full kit scope: Comprehensive high-flow solution from engine block to rear exit, including performance Tri-Y headers, premium 3" high-flow metallic catalytic converters, intermediate plumbing lines, and a signature double-skinned rear luxury-spec muffler layout.
• Direct bolt-on design maps seamlessly onto vehicle-specific factory rubber hanger positions. No custom fabrication or welding mapping required.
• Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance across extended luxury floors, strict engine bay alignment, and gas-tight seals under the floor pan.
