    Designed to Last. This Magnaflow MF Series Cat-Back Exhaust is made from tough stainless steel, making it more corrosion- and wear-resistant. This guarantees the product's durability and minimizes the need for regular maintenance checks.

    Smoother Exhaust Gas Flow. With the Magnaflow MF Series Cat-Back Exhaust installed, your vehicle gets an extra dose of horsepower, more torque, and a more responsive throttle. All this is thanks to improved exhaust scavenging and more efficient gas flow.

    Louder and Sportier Exhaust Noise. Magnaflow's MF Series exhausts aren't just about performance. These premium line exhaust systems emit a louder and more aggressive sound — something that Magnaflow systems are known for. This makes sure that you can both feel and hear the difference.
