Magnaflow Catalytic Converter

MagnaFlow: Four Decades of American Exhaust Excellence

MagnaFlow has been engineering and manufacturing exhaust products in Oceanside, California since 1981. Founded as an extension of Car Sound Exhaust, the brand spent decades developing a reputation for quality, power, and signature sound — culminating in recognition as the 2017 SEMA Manufacturer of the Year, beating out a field that included some of the most respected names in the automotive aftermarket.

What sets MagnaFlow apart from the competition starts on the shop floor. Every product is built in the USA using premium-grade stainless steel and the latest manufacturing technology. Their engineering team employs advanced 3D scanning systems during research and development to ensure precise fitment, and their straight-through muffler design minimizes backpressure for a deep, aggressive exhaust note without sacrificing performance. The result is a product lineup trusted by weekend warriors, professional builders, and emissions technicians alike.

MagnaFlow's catalog covers the full exhaust system from front to back. Their industry-leading catalytic converters are available in direct-fit and universal configurations, meeting both EPA and CARB compliance standards across a wide range of vehicles. For drivers who want a complete upgrade in one box, exhaust system kits deliver a bolt-on solution engineered for specific makes and models — no cutting or welding required. On vehicles where the manifold and converter are a single assembly, MagnaFlow's exhaust manifolds with integrated catalytic converters restore factory-like fit while improving flow and efficiency.

Rounding out the lineup, MagnaFlow performance mufflers deliver the brand's signature deep rumble using high-grade acoustical packing and corrosion-resistant stainless steel construction. For diesel truck and SUV owners, MagnaFlow also produces diesel oxidation catalysts built to OEM-grade standards, using mandrel-bent tubing and precision 3D-scanned geometry to maintain factory exhaust flow and fuel economy.

From American muscle cars and pickup trucks to SUVs, UTVs, and daily drivers, MagnaFlow has built its name on the idea that "as good as stock" simply isn't good enough. With a portfolio of over 1,400 products and a limited lifetime warranty backing their performance exhaust systems, it's easy to understand why enthusiasts and technicians keep coming back to the brand.
