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.

"went together perfect. Must have all the original rubber hangars or you will have to buy them to be able to hang this system. All parts were a perfect fit. I like the heavy duty flange were it mounts to the cat. had to go buy a new donut gasket.wasn t one in the kit. it is truly a direct bolt on system. fits great.It may be a little quitter than I thought it would be but very happy with this product" posted by: magic legs on May 8, 2014
