      Maximum Performance. The Flowmaster 50 Series HD Dual In/Dual Out Oval Muffler will give you everything your vehicle needs – improved horsepower, better throttle response, and increased mileage. Not only that, but this muffler allows for improved exhaust scavenging. It has a 2.50-Inch inlet and a 2.50-Inch outlet.

      Reduced Interior Resonance. Thanks to its three-chamber body and dual inlets and outlets, this muffler allows for a deep, moderate tone. It also reduces interior resonance.

      Tough Construction. This muffler is fully MIG welded, and it’s made using 16-gauge stainless steel. It has a black finish, and it’s resistant to corrosion, rust, and extreme under-hood temperatures.

      Direct Replacement. This muffler serves as a direct-fit replacement. Note that some adaptations, like cutting and welding, might be required, as this muffler is mounted on new hangers. If you have limited mechanical experience, it might be a good idea to take your vehicle to the mechanics and have the muffler professionally installed.

      Limited Lifetime Warranty. This muffler is covered by a limited lifetime warranty. It applies to manufacturing defects under normal use, and it can only be used by the original buyer.

      Application. The Flowmaster 50 Series HD Dual In/Dual Out Oval Muffler has a universal fit, but it’s a great fit for diesel trucks, heavy-duty gas vehicles, and trucks with modified engines. Note that it can’t be used for on-road and off-road applications as this muffler is only permitted for racing competitions.

      Installation Difficulty. Installing this muffler should take around 30 minutes to 1 hour, depending on whether you have to modify your vehicle. If no modifications are required, you’ll be able to complete this installation by yourself with some standard garage tools.
