The stock exhaust system on your 2011 to 2014 Mustang V6 isn't exactly the most efficient thing ever, and a new set of high-performance 3.7L Mustang long tube headers combined with a matching mid-pipe will give your base model Pony a huge increase in power, performance, and sound. Our Mustang V6 3.7L headers and mid-pipes are made by top-quality manufacturers like Bassani, BBK Performance, Borla, MRT and more. These powerful exhaust parts keep your Mustang's exhaust system almost entirely free of back pressure, allowing your engine to breathe easier and let exhaust gasses escape its cylinders more easily. The result is an impressive gain in horsepower and torque, especially when paired with a powerful custom tune. Once you have a set of headers and a mid-pipe selected, take a look at our Mustang V6 3.7L Mustang Axle Back exhaust kits.
