Move exhaust gases off the cylinder head and treat them in a single bolt-on unit with the Eastern Catalytic Exhaust Manifold with Integrated Catalytic Converter (P/N 40800). It installs as a direct-fit replacement for the 2007-2012 Nissan Altima, combining the front exhaust manifold and the catalytic converter into one assembly.
Manifold + converter in one: collects exhaust from the cylinder head and routes it through the integrated catalyst.
Emissions treatment: the catalyst reduces regulated exhaust emissions as gases pass through it.
Front position: serves as the front exhaust manifold assembly on the listed application.
Direct-fit: designed to replace the original unit on the 2007-2012 Nissan Altima.
Signs this part may need replacing include a rattle from a broken catalyst substrate, exhaust leaks at the manifold, or an illuminated check engine light. If a failed manifold-mounted converter is the cause of a converter-efficiency trouble code, this assembly replaces it — diagnose the cause before ordering, since these symptoms can have other sources.
Interchange: Manufacturer part number 40800.
