Advance Headers High-Performance Mild Steel Exhaust Extractors for HOLDEN Commodore VZ, Statesman WL & Crewman 2WD 3.6L Alloytec V6
The Advance Headers Performance Exhaust Extractors (A230) are precision-engineered for the modern 3.6-Litre Alloytec DOHC V6 engine family introduced across Holden's VZ and WL generations. This heavy-duty tubular header upgrade replaces your highly restrictive and heat-retaining factory cast iron manifolds, dramatically dropping backpressure to optimize exhaust gas velocity, sharpen throttle response, and unlock true performance torque across the rev range.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Performance Exhaust Extractor Header Set (Left & Right Bank Assembly)
Key Features:
- Tuned mandrel-bent primary piping pathways ensure completely uniform gas flow routing, eliminating the heavy restrictions found in original cast manifolds
- Substantially optimizes overall exhaust gas scavenging velocity, delivering crisper throttle response and noticeable low-to-mid range torque gains for the DOHC architecture
- Heavy-duty mild steel construction structurally built to handle severe thermal expansions and demanding street-performance heat cycles safely
- Thick, precision laser-cut cylinder head flanges maintain flush mating boundaries to guard permanently against warping and exhaust gas leaks
- Engineered specifically for Front-Engine, Rear-Wheel Drive (RWD) 2WD layouts to navigate engine bay path boundaries and steering columns cleanly

⚠️ Crucial Drivetrain Fitment Compatibility Note:
This extractor set (Part No. A230) is engineered strictly for 2WD (Two-Wheel Drive / Rear-Wheel Drive) configurations. Due to unique underbody clearance paths and physical space limits around the transfer case and front driveshaft assemblies, this kit will NOT fit Adventra or Crewman Cross 6 / Cross 8 AWD (All-Wheel Drive) models. Please confirm your drivetrain specifications prior to placing an order.
Please Note: Professional installation by an exhaust specialist or qualified automotive mechanic is highly recommended to guarantee proper system alignment and a perfect gas-tight seal.
