Advance Headers High-Performance Mild Steel Exhaust Extractors for HOLDEN Commodore VS 3.8L Ecotec V6 (Hydraulic Manual Models)
The Advance Headers Performance Exhaust Extractors (A228M) are precision-engineered for the legendary 3.8-Litre Ecotec V6 engine paired with a hydraulic manual transmission layout in the Holden Commodore VS series. This heavy-duty tubular header upgrade replaces your highly restrictive factory cast-iron manifolds, meticulously curved to clear underbody hydraulic slave cylinder components while dropping backpressure to optimize exhaust gas velocity and deliver crisper engine response.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Performance Exhaust Extractor Header Set (Left & Right Bank Assembly for Hydraulic Manuals)
Key Features:
- Custom-clearanced routing configuration specifically engineered to bypass hydraulic manual slave cylinders and clutch lines safely
- Tuned mandrel-bent primary piping pathways ensure completely uniform gas flow routing, eliminating the heavy restrictions found in original factory manifolds
- Substantially optimizes overall exhaust gas scavenging velocity, delivering sharper throttle response and noticeable low-to-mid range torque gains
- 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

⚠️ Crucial Steering Rack & Transmission Compatibility Warnings:
1. Transmission Restrictions: This part number (A228M) is built exclusively for Hydraulic Manual models. It will NOT fit clutch cable manual configurations due to interference with the physical cable mechanisms and pedal bracket paths. (For standard automatics, please look at part number A228).
2. Steering Rack Restriction: Because of the specialized housing dimensions required by electronic variable-effort steering systems, this header assembly will NOT fit models equipped with a Variable Speed Steering Rack (variatronic steering setups found on select premium Calais or Statesman variants). Please inspect your steering layout prior to ordering.
Please Note: Professional installation by an exhaust specialist or qualified automotive mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
