Advance Headers High-Performance Mild Steel Exhaust Extractors for HOLDEN Commodore VL 253 & 308 V8 Swaps
The Advance Headers High-Performance Exhaust Extractors (A313) are precision-engineered for classic Holden Commodore VL platforms running the legendary 4.2-Litre 253ci and 5.0-Litre 308ci iron-block V8 engines. Specifically developed as a true high-performance header upgrade, this heavy-duty tubular system features optimized collector matching that bolts directly up to the factory or aftermarket catalytic converter flange assembly. By replacing highly restrictive cast iron manifolds or standard generic block huggers, this kit maximizes scavenging velocity, balances cylinder tuning, and delivers that signature deep, crisp classic Aussie V8 roar.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel High Performance Exhaust Extractor Header Set (Left & Right Bank Assembly)
- 1 x Dedicated High-Flow Collector Pipe Section (Engineered to route cleanly to the catalytic converter)
Key Features:
- High-performance layout features optimized mandrel-bent primary pathways to ensure completely uniform gas flow velocity and maximize high-RPM breathing efficiency
- Integrated catalytic converter hookup design allows the trailing collector to mate seamlessly up to the cat flange boundaries with zero custom downpipe fabrication required
- Substantially optimizes low-to-mid range torque acceleration—giving modified street cruisers, tough muscle swaps, and street/strip cars a notable performance boost
- Heavy-duty mild steel construction structurally built to handle intense under-bonnet V8 thermal transitions and demanding high-performance heat cycles safely
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping and high-pressure exhaust leaks

⚠️ Crucial Model Application & Drivetrain Fitment Notes:
1. Chassis Specifics: This product (Part No. A313) is configured explicitly for the Holden Commodore VL series engine bay boundaries. Due to differing front K-frame contours, steering rack placements, and firewall line tracks, it will not drop correctly into earlier VK, VH, VC, or VB engine bays or later VN-VS generations without structural interference.
2. Engine Valve-Train Limits: This kit is tailored strictly for standard Holden 253 and 308 iron heads. It will not align with later fuel-injected VN-style cylinder heads (Holden 304/5.0L running high-port symmetrical configurations) due to entirely different exhaust port shapes and flange bolt alignments.
Please Note: Professional installation by an exhaust specialist or qualified automotive mechanic is highly recommended to guarantee proper system mapping and a perfect leak-free seal.
