The Magnaflow 60504 OEM Grade Direct-Fit Diesel Oxidation Catalyst (DOC) from XDP is a direct replacement for the clogged catalyst in your 2007.5-2010 GM 6.6L Duramax LMM. This DOC has mandrel bent tubing, stainless steel construction for long-term durability, and all new hardware for easy installation. This catalyst is built to your factory catalyst's exact specifications and is designed to be a drop-in replacement. The laser fusion weld considerably decreases the chance of a leak by replicating the OE spun body design, and the compact, low-mass design also increases thermal efficiency. This catalyst is simple to mount and is engineered to work with your existing equipment.
