Product Description

The MagnaFlow 93689 is an HM Grade Federal/EPA direct-fit catalytic converter designed specifically for the 1999-2004 Land Rover Discovery Series II. Built to exact OEM specifications using MagnaFlow's 3D scanning metrology process, this converter installs as a bolt-on replacement without cutting, welding, or fabrication. The HM Grade designation indicates an elevated catalyst loading beyond standard grade, improving the conversion of harmful exhaust gases including hydrocarbons, carbon monoxide, and nitrogen oxides. Four OEM-matched O2 sensor ports ensure seamless integration with the Discovery's upstream and downstream oxygen sensors, keeping the check engine light off after installation.

Constructed from mandrel-bent stainless steel tubing with a ribbed body and continuous seam-weld, this converter is built to withstand the thermal cycling and corrosion demands of long-term use. The ceramic monolithic substrate is coated using a strictly controlled process to maintain exact catalyst specifications and prevent flow restriction. This part is Federal/EPA compliant for 49-state use and is not approved for sale or use in California or other CARB-regulated states. Exhaust gaskets are not included and should be sourced separately prior to installation. Backed by MagnaFlow's limited lifetime warranty and made in the USA.
