Magnaflow Catted X-Pipe (50 State Legal) - Stainless Steel
Replace your failing catalytic converters on your 1999-2004 with the Magnaflow direct fit catted X-pipe. This Magnaflow catted X-Pipe is the answer to your problem! With four integrated high-flow cats, this X-Pipe cuts down emissions while improving exhaust flow giving you more horsepower and a more aggressive exhaust tone! MagnaFlow's Mustang Catalytic Converter is designed to do two jobs: Reduce Emissions and Improve Flow. The emission-reducing task is taken care of by two high-efficiency ceramic catalysts that use heat and a precious metal coating to burn off harmful elements. Flow improvements are accomplished by utilizing fast-flowing mandrel-bent tubing and incorporating MagnaFlow's Tru-X crossover pipe that replaces the inefficient factory h-pipe. Designed to work with both the stock manifold or short tube headers for a simple and easy installation. MagnaFlow makes both a 50-State-legal Mustang converter, as well as an off-road Tru-X crossover pipe without converters.
