Performance Muffler. The Flowmaster Super 40 Series Dual In/Dual Out Oval Muffler with 2.50-Inch inlet and outlet delivers a deep, aggressive exhaust note ideal for enhancing the sound and performance of high horsepower vehicles. It improves exhaust flow efficiency while reducing interior resonance for a more refined driving experience. This muffler is commonly used on street and strip vehicles, muscle cars, trucks, and SUVs looking for a bold sound combined with strong performance gains.
_x000D__x000D_Construction and Appearance. Crafted from durable 16 gauge 409 stainless steel, this muffler features a larger, oval-shaped chamber body for optimized flow and sound control. The fully MIG welded construction ensures maximum strength and longevity, while the natural finish highlights its rugged stainless steel texture. The robust design provides resistance to corrosion and rough use in performance applications.
_x000D__x000D_Installation. Installation requires moderate mechanical skill, with slip-fit dual inlet and outlet connections designed for clamp-on or weld-on mounting. No additional drilling is generally needed, though new hangers are required as none are included.
_x000D__x000D_Application. Fits universal applications across 4 and 6-cylinder engines, classic and late model muscle cars, street rods, street/strip vehicles, and trucks/SUVs. Some adaptation may be required to achieve proper fitment depending on the vehicle’s exhaust configuration.
