Description
Original Flowmaster Sound. The Flowmaster 40 Series Offset/Center Oval Muffler with 3-Inch Inlet and 3-Inch Outlet delivers a distinct aggressive exhaust tone favored by muscle car and performance truck enthusiasts. It enhances both exterior sound and interior resonance, making it ideal for street, strip, and off-road applications, providing a powerful auditory presence and performance improvement.
Construction and Appearance. Made from durable 16-gauge aluminized steel, this chambered muffler features fully MIG-welded seams for long-lasting strength and durability. It is finished with high-temperature black paint, giving it a sleek, aggressive appearance that withstands harsh conditions and heat exposure.
Installation. Installation is straightforward with slip-fit inlet and outlet connections suitable for clamp-on or weld-on methods. No drilling is required, but the muffler uses new hangers which are not included, so additional adaptation may be necessary.
Application. This exhaust muffler offers universal fitment, suitable for a wide range of classic and late-model muscle cars, street rods, trucks, and SUVs. Some adaptation may be required for specific vehicle installations.
