Exhaust System with Catalytic Converter for Honda Accord (2006-2007) 2.4L

Direct-Fit 409 Stainless Exhaust System with Catalytic Converter for 2006-2007 Honda Accord (CM5/CM7)

What it Does: This complete 409 stainless steel exhaust and dual-converter kit restores factory emissions compliance and quiet flow on 2006-2007 Honda Accord (CM5/CM7) K24 2.4L vehicles.

The Stock Honda Accord Exhaust Failure

On the seventh-generation CM5/CM7 Honda Accord equipped with the K24 2.4L engine, thermal cycling and road salt corrode the thin factory exhaust flanges, muffler seams, and resonator baffles. Simultaneously, prolonged heat soak fractures the ceramic substrate inside the front manifold and intermediate catalytic converters. Once exhaust leaks draw air past the oxygen sensors or catalyst efficiency drops, the ECU logs a persistent P0420 check engine code.

Common Symptoms of a Failing OEM Exhaust System

• Check Engine Light: Logs P0420 catalyst efficiency codes from degraded washcoat or pre-sensor exhaust leaks.
• Rattles & Leaks: Fractured ceramic bricks rattle inside the converter shell while rusted flanges hiss under load.
• Failed Emissions & Backpressure: Clogged substrates restrict exhaust scavenging, hurting throttle response and OBD-II inspection readiness.

The Direct-Fit 409 Stainless Exhaust Solution

Built from corrosion-resistant 409 stainless steel, this full assembly replicates OEM routing with mandrel-bent tubing, factory-style flanges, and stock hanger locations. Both the front manifold converter and intermediate converter house EPA-rated ceramic honeycomb substrates engineered to stabilize downstream oxygen readings and maintain quiet factory acoustics. Every junction uses direct bolt-on flanges or slip joints without cutting or welding, directly replacing OEM references 506158, 103168, and 302132.

Frequently Asked Questions & Fitment Warnings

Does this fit the CM5/CM7 Accord?

Yes. This is a direct fit for the 2006-2007 Honda Accord equipped with the K24 2.4L engine. It does not fit 2003-2005 or 2008-and-later Accords, and it 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, new converters resolve P0420 efficiency faults, though O2 sensors are not included. Inspect and reuse healthy factory oxygen sensors, or replace fouled units before clearing ECU codes.

Is welding needed, and are gaskets included?

No welding is required. All flange and slip joints bolt together using the supplied ring gaskets, flange gasket, U-clamps, and hardware.
