Cut harmful tailpipe emissions and get your exhaust back into compliance with the Walker Exhaust Ultra Direct-Fit Catalytic Converter 54809, cataloged by Walker as a direct-fit for the Nissan Murano. It drops in as a bolt-on replacement — see the Buyer's Guide tab for the exact years and engine applications, and confirm fitment for your vehicle before ordering.
- Direct-fit bolt-on design: installs with factory-style heat shields, routings, brackets, and hangers, so the job doesn't require special fabrication or welding.
- Round stainless steel body: built with a 3-bolt welded inlet flange and a 2-bolt welded outlet flange; the outlet measures 2.505 in outside diameter.
- OE-style washcoat and precious-metal load: designed to deliver the required reduction in tailpipe emissions to match the vehicle application. If a failed converter is setting an emissions code, this replaces it.
- Backed by Walker: covered by 25,000-mile/40,000-kilometer emissions coverage and 5-year 50,000-mile/80,000-kilometer structural-integrity coverage (see Walkerexhaust.com for details).
