Advance Headers | Stainless Steel Exhaust Extractors | Mitsubishi Pajero NS V6 3.8L 3 Cat Model | A349PSS

PRODUCT CONTENTS:

• 1 x Premium Stainless Steel Performance Left-Hand Decat Extractor Header Assembly
• 1 x Premium Stainless Steel Performance Right-Hand Decat Extractor Header Assembly

Key Features:

• High-grade stainless steel construction provides ultimate defense against under-car atmospheric moisture, beach salt rust, mud scaling, and harsh off-road thermal stress cycles
• Performance-tuned layout deletes the two restrictive top primary catalytic converters directly off the cylinder heads, clearing out massive exhaust backpressure bottlenecks entirely
• Substantially optimizes low-to-mid range torque delivery—ideal for restoring throttle response, climbing steep off-road tracks, and maintaining highway overtaking power under heavy towing loads
• Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and high-pressure exhaust gas leaks
• Mandrel-bent primary pipelines maintain perfectly uniform internal diameters, allowing smooth, uninhibited gas velocity transitions

⚠️ Crucial Emissions Compliance & Model Matching Warnings:
1. Primary Cat Deletion Architecture: This product (Part No. A349PSS) is an off-road track performance layout that physically deletes the top 2 catalytic converters built into the standard factory manifolds. It retains standard tracking down to the main remaining secondary cat path. An aftermarket ECU re-tune or oxygen sensor spacer modification may be required to clear potential emissions dash faults.
2. Date Constraint Limitation: Mapped strictly for the post-October 2006 NS series generation onwards running the 3-cat emissions system block layout. Will not substitute cleanly onto earlier NM-NP single cat platforms.

Please Note: Due to the deletion of the primary manifold catalytic converters and exact oxygen sensor indexing required, professional installation by an exhaust specialist or qualified 4WD performance technician is highly recommended.
