Advance Headers High-Performance Mild Steel Exhaust Extractors for Holden Adventra & Crewman Cross 8 AWD Gen III 5.7L V8 Platforms
The Advance Headers Performance AWD Exhaust Extractors (A318) are precision-engineered exclusively for Holden's heavy-duty All-Wheel Drive (AWD) V8 platforms. Tailored specifically to solve the extreme clearance headaches presented by the complex packaging under Holden Adventra wagons and Crewman Cross 8 dual-cab utilities, this tubular upgrade is mapped around the General Motors 5.7-Litre Gen III LS1 V8 powerplant. By completely replacing the restrictive factory cast iron manifolds, this high-flow system routes around front transfer cases and additional driveshafts to maximize scavenging velocity, boost low-to-mid range torque, and unleash a crisp performance V8 bark.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Left-Hand AWD Specific Extractor Header Assembly
- 1 x Heavy-Duty Mild Steel Right-Hand AWD Specific Extractor Header Assembly
Key Features:
- Engineered specifically for All-Wheel Drive architecture, utilizing highly customized primary tube routing to step cleanly around front-wheel differential housings, transfer cases, and intermediate driveshafts
- Tuned mandrel-bent primary pathways maintain a completely uniform internal diameter, eliminating the harsh restrictions and localized heat traps found in standard log manifolds
- Substantially optimizes low-end torque delivery and mid-range throttle acceleration—providing crucial towing, heavy-load hauling, and rugged all-terrain pulling power
- Heavy-duty mild steel construction structurally built to absorb intense thermal transitions, high chassis stress cycles, and corrugated track off-road vibrations safely
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion and high-pressure exhaust gas leaks

⚠️ Crucial Drivetrain Application Profile Constraint:
This product (Part No. A318) is formatted and bent explicitly for Holden CrossTrac All-Wheel Drive platforms. Due to the asymmetric tube profiling and clearance adjustments needed to wrap around front axle assemblies, it will NOT fit standard rear-wheel-drive (RWD) Commodore sedans, standard utilities, or Monaro models safely. Please ensure your vehicle is an authentic AWD crossover or commercial build variant before finalizing your order.
Please Note: Due to the exceptionally dense routing configurations beneath the CrossTrac AWD underbody, professional installation by an exhaust specialist or qualified 4WD/AWD mechanic is highly recommended to guarantee proper system mapping and a perfect leak-free seal.
