Advance Headers High-Performance Mild Steel Exhaust Extractors for Mitsubishi L300 2WD & 4WD Sirius Engines
The Advance Headers Performance Exhaust Extractors (A343) are precision-engineered to upgrade the power delivery and efficiency of the classic Mitsubishi L300 commercial vans, campers, and heavy-duty four-wheel-drive lines running the famous Sirius engine platform. Built as a rugged tubular upgrade to replace highly restrictive factory cast iron manifolds, this system drops exhaust backpressure and drastically improves cylinder gas scavenging velocity. By clearing out hot spent gases rapidly, it unlocks critical low-to-mid range working torque and improves engine throttle response under load.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Performance Exhaust Extractor Header Assembly
Key Features:
- Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and eliminating heavy factory casting restrictions
- Substantially optimizes low-to-mid range torque delivery—ideal for moving heavy commercial cargo, navigating steep off-road trails, and holding highway cruising speed when fully loaded
- Heavy-duty mild steel construction structurally built to handle intense under-floor thermal transitions and demanding commercial operation safely
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping, face distortion, and high-pressure exhaust leaks
- Engineered for an exceptionally fast workshop turnaround, featuring an estimated baseline installation time of just 1.5 hours

- Component Type: Performance Exhaust Extractors / Headers
- Estimated Fitting Time: 1.5 Hours
- Welding Required: No (Direct Bolt-On Configuration to Cylinder Head)
⚠️ Crucial Drivetrain & Engine Block Verification:
This product (Part No. A343) is designed explicitly around the clearance bounds of the Mitsubishi Sirius motor block architecture in the L300 chassis layout. The plumbing pathways are custom-formed to clear both standard low-slung 2WD front subframes and the bulky front differential drop housings found on 4WD van variants. Please ensure your engine series is verified as part of the early SOHC Sirius block family before finalizing your purchase.
Please Note: Professional installation by an exhaust specialist or qualified commercial mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
