Exhaust System for Honda CR-V (2005-2006) 2.4L

409 Stainless Exhaust System with Converter for 2005-2006 Honda CR-V (RD6/RD7)

What it Does: This 409 stainless steel exhaust and catalytic converter system replaces the corroded factory piping from front converter to rear muffler on 2005-2006 Honda CR-V RD6/RD7 models with the K24 2.4L engine.

The Stock Honda CR-V Exhaust Failure

On second-generation RD6/RD7 vehicles equipped with the K24 2.4L four-cylinder, thermal cycling, moisture condensation, and road salt cause the factory front converter pipe, mid-section, and rear muffler to rust through together. Flange welds delaminate and ceramic substrates fracture from heat soak, creating exhaust leaks upstream of the rear oxygen sensor. Skewed post-catalyst O2 readings then trigger P0420 catalyst efficiency faults alongside cabin fumes and metallic rattles.

Common Symptoms of a Failing OEM Exhaust System

• Check Engine Light / DTCs: Stored P0420 catalyst efficiency codes caused by degraded substrate or pre-sensor exhaust leaks.
• Physical/Audible Signs: Metallic rattling from fractured converter bricks and loud booming or ticking from corroded flange joints.
• Drivability/Compliance Impact: Failed OBD-II emissions inspections, noxious exhaust odor, and restricted flow from collapsed muffler baffles.

The 409 Stainless Direct-Fit Exhaust Solution

Built from corrosion-resistant 409 stainless steel, this complete assembly replaces OEM/interchange part numbers 16167, 56194, and 54427 in one service job. Mandrel-bent tubing preserves smooth exhaust flow geometry, while factory-style flanges and hanger rods maintain exact underbody clearance and quiet stock acoustics. The front converter pipe includes two stock-position O2 sensor bungs and a ceramic honeycomb substrate for bolt-on installation without cutting or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the RD6/RD7 CR-V?

Yes. This is a direct fit for the 2005-2006 Honda CR-V equipped with the K24 2.4L engine. It does not fit 2002-2004 or 2007-2009 CR-V models, and is not legal for sale or use in California, Colorado, New York, or Maine.

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

Yes, replacing a failed converter and leaking pipes resolves P0420 faults when sensors are healthy. New O2 sensors are not included; transfer your functioning factory sensors into the two stock-position bungs.

Are gaskets and mounting hardware included for installation?

Yes. Every flange and slip joint seals with the supplied ring gaskets, flange gasket, U-clamp, spring bolts, springs, bolts, nuts, and washers with zero welding required.
