Magnaflow Performance Exhaust Systems

MAGNAFLOW PERFORMANCE EXHAUST SYSTEMS

Over the past 30 years, Magnaflow has grown as a market leader of exhaust systems, focusing on three key elements with each product they produce—quality, power and sound. Magnaflow’s Performance exhaust systems feature stainless steel construction and mandrel bent pipes, allowing for greater fuel economy and improved performance. A full-bodied exhaust note, emblematic of the brand, is achieved through the smooth, lap-joint welded body, tightly packed with acoustical fibers designed to dampen irritating pitch tones.
