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.

Customer Review: (see review/s)
  • This exhaust fit my Armada exactly. It has a nice sound to it and I can feel extra pick-up when hitting the gas.

  • Was installed easy with the exception of the tail pipe end. Could not lift car off the ground high enough to twist pipe in place over axle. Took it to a body shop and had them lift it so I could install the last piece. Got it done in 1.5hrs. The exhaust system is louder than the stock and it feels like it did get some extra boost as I tested it on the highway. Overall I say it was a good buy hopefully it will last longer than the stock exhaust system.
