Catalytic Converter for Mitsubishi Raider (2006-2009) 3.7L 4.7L

Direct-Fit Stainless Catalytic Converter Y-Pipe for 2006-2009 Mitsubishi Raider (ND)

What it Does: This direct-fit stainless steel catalytic converter Y-pipe for the 2006-2009 Mitsubishi Raider (ND) with the EKG 3.7L V6 or EVA 4.7L V8 converts toxic exhaust gases while restoring factory flow.

The Stock Mitsubishi Raider Catalyst Failure

On the ND chassis Raider equipped with the EKG 3.7L V6 or EVA 4.7L V8, thermal cycling and road-salt corrosion fatigue the factory Y-pipe shells and flange welds. Unburned fuel spikes and extreme exhaust heat fracture the internal ceramic honeycomb substrate or cause it to separate from its mat insulation. Once oxygen storage drops below threshold, the PCM triggers P0420/P0430 codes and chokes exhaust scavenging.

Common Symptoms of a Failing OEM Catalytic Converter

• Check Engine Light / DTCs: Downstream O2 sensors detect poor conversion efficiency, setting P0420 or P0430 codes.
• Metallic Substrate Rattle: Broken ceramic pieces rattle inside the converter body on cold starts and acceleration.
• Power Loss & Emissions Failure: Collapsed substrate raises exhaust backpressure, cutting throttle response and failing OBD-II inspections.

The Direct-Fit Stainless Catalytic Converter Solution

This single-piece Y-pipe integrates dual bank catalysts into a corrosion-resistant stainless steel assembly engineered to match factory manifold flanges on the ND platform. Each converter houses a ceramic honeycomb substrate with a precious-metal washcoat to oxidize HC and CO while reducing NOx emissions. Precision pre- and post-catalyst sensor ports preserve OEM oxygen sensor geometry for accurate OBD-II monitoring, requiring no cutting or welding during installation.

Frequently Asked Questions & Fitment Warnings

Does this fit the ND Raider?

Yes. Fits 2006-2009 models with the EKG 3.7L V6 and 2006-2007 models with the EVA 4.7L V8. Excludes 2008-2009 4.7L V8 trucks; EPA federal unit is not CARB-approved and cannot ship to or be used on vehicles registered in CA, NY, CO, or ME.

Will this clear P0420/P0430 codes, and are O2 sensors included?

Yes, when the catalyst has failed. New precious-metal substrate restores conversion efficiency to clear P0420/P0430 codes once exhaust leaks and faulty sensors are ruled out; O2 sensors are not included.

Is installation hardware included?

Outlet clamp included. Soak manifold bolts with penetrating oil before removal, use new flange gaskets, and torque fasteners evenly before checking every joint for leaks.
