Moderate Sound. Unlike other aftermarket mufflers, the Flowmaster Super 50 Series HD Muffler won’t produce a deafening, obnoxious noise. Designed for today's heavy duty gas and diesel trucks, this muffler delivers improved performance, throttle response and mileage with a deep, moderate tone.
Superior Design. Made in America, this Super 50 Series HD Oval Muffler is MIG welded from durable 16 gauge 409S stainless steel for extreme durability and value. Super 50 Series HD Mufflers produces minimal interior resonance and is ideal for trucks with modified engines. Each muffler is embossed with the "Flowmaster" name so you know it is the real article.
Modifications Required. This Muffler was designed to be used on multiple applications, as it is not a direct fit replacement part. In order to install this Muffler properly on your vehicle, some modifications to the exhaust system may be required.
Application. This Flowmaster Super 50 Series HD Muffler's outer case measures 5 x 10 x 18 inches, and features a 3.50-inch offset inlet and 3.50-inch offset outlet configuration. This is the perfect muffler for universal applications.
