PRODUCT CONTENTS:

Key Features:

• Tuned mandrel-bent primary piping pathways map perfectly to the high-port symmetrical Holden EFI cylinder heads, ensuring completely uniform gas flow routing and maximizing engine efficiency
• Substantially optimizes low-to-mid range torque delivery and throttle response—providing critical extra acceleration grunt for modified street builds and daily high-performance driving
• Heavy-duty mild steel construction structurally built to handle intense under-hood thermal transitions and demanding V8 operational heat cycles 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 leaks

Specifications:

⚠️ Crucial Engine Family Fitment Warning:
This product (Part No. A315) is configured explicitly for the traditional Australian 5.0L Holden V8 iron block engine utilized strictly in the VT Series I production run between 1997 and 1999. It will NOT fit later VT Series II models or subsequent generations, as Holden transitioned completely to the all-aluminum General Motors 5.7L Gen III LS1 V8 engine, which features completely disparate port spacings and bolt track patterns.

Please Note: Professional installation by an exhaust specialist or qualified classic automotive mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
