Exhaust Manifold with Catalytic Converter

The MagnaFlow 50380 manifold with Heavy Metal catalytic converter is made with heavy-duty steel for superior strength and durability. The manifold collects exhaust fumes, and the catalytic converter transforms it into a less dangerous emission.

Mandrel Bent Pipes

The tubes are mandrel-bent for unrestricted flow of your Infiniti QX56's exhaust gases. This prevents backflow to allow the engine to perform at optimum speeds. The result is increased performance and better gas mileage.

Monolithic Honeycomb Catalyst Design

The converter features a monolithic honeycomb design for the catalyst. It increases the exhaust flow surface area for maximum conversion even with high exhaust volumes.

Ribbed Body

The MagnaFlow 50380 manifold with Heavy Metal catalytic converter has a ribbed heat shield that provides a rigid wall for heat protection. It creates a stable structure to contain the hottest exhaust fumes.

Easy to Install

It is easy to install- the package comes with all the hardware necessary for installation. It also includes a set of instructions to help you go about it quickly and easily. It, however, recommended that you seek the service of a professional to avoid damages during installation.

Direct Fit Design

The manifold and converter are designed to fit your Infiniti QX56 perfectly. Just verify your vehicle's information using our fitment checker above.

Heavy Stainless Steel Construction

The MagnaFlow 50380 manifold with Heavy Metal catalytic converter is made with premium-grade stainless steel that won't rust, oxidize or corrode. It stays strong for years and takes all the heat to maintain its hold.
