Premium Performance Muffler. The Flowmaster 40 Series Delta Flow Center/Dual Out Oval Muffler with 2.50-inch inlet and 2.50-inch outlet delivers an aggressive exhaust sound designed for street, strip, and off-road applications. It enhances performance by increasing exhaust scavenging while reducing interior resonance for a milder tone inside the vehicle. This muffler is ideal for performance enthusiasts seeking to improve sound and efficiency.
_x000D__x000D_Construction and Appearance. Built from durable 16 gauge aluminized steel, the muffler features full MIG welding to ensure maximum strength and longevity. Its oval body is coated with high-temperature paint, providing resistance to heat and corrosion while maintaining a sleek finish under the vehicle.
