Don’t hold your ride back with stock cat converters, especially when upgrading is as easy as installing a set of Magnaflow Catalytic Converters (50-State Legal). If you’re looking for fast-flowing exhaust and enhanced engine efficiency, then this is the ultimate solution to the P0420 Diagnostic Trouble Code.
Fashioned from 16-gauge stainless steel, filled with precious metals and sealed with welded seams for ultra-durability and flow, these replacement converters have a unique, honeycomb-shaped pattern to maximize their internal surface area. This allows more exhaust to escape faster.
Designed, just as their name implies, for a direct-fit, they meet strict California Air Resources Board (CARB) emissions standards, and carry with them a 5-year/50,000-mile external warranty and 2-year/25,000-mile internal warranty.
