Pacemaker Full 3" Performance Exhaust System with 1 3/4" 4-into-1 Headers & Hi-Flow Cats for HSV VF Gen-F Maloo Utility (6.2L LS3 V8) - PP5381-68

Extract massive high-RPM horsepower, optimize heavy gas velocity tracking, and unleash a commanding, deep muscle car roar from your Gen IV small-block with the Pacemaker Sport Systems complete large-bore 3-inch performance exhaust solution featuring premium 1 3/4" 4-into-1 headers. Custom-engineered specifically to handle the extraction demands, extreme thermal stress, and acoustic thresholds of the high-performance HSV 6.2L LS3 V8 engine configuration, this high-flow system is precision-molded to clear the distinct utility floor pan lines, flat load tray beds, and multi-link independent rear suspension geometry of the VF series commercial performance architecture. Designed explicitly to interface flawlessly with your vehicle's factory fixed exhaust tips integrated into the rear bumper fascia, this premium kit delivers seamless aesthetic alignment. By pairing race-proven 1 3/4" 4-into-1 primary extractor pipes with smooth, mandrel-bent 3" plumbing and a premium high-flow cat section, it rapidly clears spent gases to completely eradicate 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, producing an authoritative performance rumble outside while actively engineering out harsh interior cabin boom or tray cavity resonance to ensure a clean, drone-free highway cruise. Note: Fits HSV VF Gen-F Maloo Utility (Ute) models built from May 2013 to September 2015 equipped with the 6.2L LS3 V8 engine configuration and factory fixed bumper exhaust tips; does not fit Sedan, Sportwagon, or long-wheelbase Grange variants due to structural routing constraints.

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 iconic HSV VF utility tray platform.

• Complete Headers & Full System: Comprehensive track-and-street performance solution incorporating high-flow 1 3/4" 4-into-1 headers, 3" metallic high-flow catalytic converters, and a full matching large-bore 3-inch performance intermediate-to-rear utility exhaust layout.
• 4-into-1 Design Architecture: Race-proven extractor layout featuring precision-formed 1 3/4" primaries running into a merged collector to optimize top-end gas scavenging and unlock significant power gains.
• Factory Fixed Tip Integration: Specific tailpipe outlets engineered explicitly to slide directly into and align perfectly with the standard fixed chrome exhaust tip bezels built into the factory rear Maloo bumper bar.
• 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 open utility cabs 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 constraints.
• 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 HSV VF Gen-F Maloo Utility (Ute) models powered by Gen IV 6.2L V8 LS3 engine configurations built from May 2013 to September 2015.
• Bumper Tip Requirement Configuration: This kit is specifically tailored for early VF Gen-F Maloo builds that feature factory fixed rear chrome exhaust outlets integrated into the rear bumper fascia. The tailpipes feature an open-ended configuration designed to seat cleanly within those factory bezels without heat mapping issues. It will not adapt correctly to models requiring standard exhaust tips attached directly to the muffler cans.
• Utility Specific Chassis Layout: Due to the floor cavity profiles, cargo tray structures, and rear utility hanger paths unique to the Ute body style, this configuration features length-specific intermediate and rear plumbing sections. It will not adapt cleanly to Sedan, Sportwagon, or long-wheelbase platforms without modification.
• Full kit scope: Comprehensive high-flow solution from engine block to rear exit, including 1 3/4" 4-into-1 headers, premium 3" high-flow metallic catalytic converters, large-bore 3" intermediate plumbing paths, and a signature double-skinned rear utility muffler layout 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, strict steering column tracking clearance, correct placement within fixed rear bumper bezels, and gas-tight seals under the floor pan.
