Description
Original Flowmaster Sound. The Flowmaster 40 Series Center/Dual Out Oval Muffler with a 3-Inch inlet and 2.50-Inch outlet provides an aggressive exhaust tone both outside and inside the vehicle. This muffler is designed for performance enthusiasts looking to achieve the iconic Flowmaster sound, ideal for street, strip, and off-road applications.
_x000D__x000D_Construction and Appearance. Constructed from durable 16 gauge 409 stainless steel, the muffler is fully MIG welded to ensure maximum strength and longevity. It features a high-temperature black paint finish that resists heat and corrosion, maintaining its aggressive appearance over time.
_x000D__x000D_Installation. The muffler installs with slip-fit inlet and outlet connections designed for clamp-on or weld-on mounting. Installation requires basic mechanical skills. New hangers are required but not included, and some adaptation may be needed due to its universal fitment.
_x000D__x000D_Application. This muffler fits a wide range of vehicles including classic muscle cars, late model muscle cars, street rods, street/strip vehicles, and trucks/SUVs; however, it is universal and may require adaptation for specific installations.
