Aggressive Performance Exhaust. The Flowmaster Super 10 Series Dual In/Dual Out Oval Muffler; 2.50-Inch Inlet/2.50-Inch Outlet delivers a loud, aggressive exhaust note designed primarily for off-highway use. This muffler is engineered to enhance exhaust flow and maximize performance, making it ideal for muscle cars, street rods, and trucks looking for a bold sound and significant power gains.
Construction and Appearance. Crafted from durable 409S stainless steel with 16-gauge thickness, this muffler features fully MIG welded construction for longevity and resistance to corrosion. Finished in high-temperature black paint, it offers a rugged look while protecting against high heat and wear.
Installation. Installation typically requires moderate mechanical skill with no special drilling necessary due to slip-fit connections. New hangers are needed as they are not included, and some adaptation may be required because of the universal design.
Application. Designed for universal fitment where some adaptation may be required, this muffler suits classic and late model muscle cars, street rods, street/strip applications, and trucks or SUVs. It is not recommended for street-driven vehicles due to its aggressive sound level.
