Performance. Made in the USA, this individually sold MWA Superflow Muffler features a straight-through design for better volume efficiency with unrestricted flow. Typical factory mufflers can have 34% or more exhaust restriction and some aftermarket mufflers can have over 20% restriction. This Gibson Superflow Muffler only has about a 5% restriction because Gibson custom power-tunes their mufflers. Keeping the opening diameter of the pipe constant by "mandrel bending", even through the bends, allows the exhaust pulse to flow smoothly without power robbing restrictions or backup.

Impressive Acoustics, Easy Installation. With a 2.5" offset inlet and 2.5" center outlet, this MWA Superflow Muffler produces a notable audible increase over stock mufflers, yet minimizes drone and sound transfer to the vehicle cabin. Designed to comply with sound and emission regulations, this muffler is safe to install without worrying about the boys and girls in blue.

Warranty. Gibson provides a Limited Lifetime Warranty for this MWA Muffler.

Application. This Gibson 2.5 in. Stainless MWA Superflow Offset/Center Oval Muffler is designed for any 1997-2017 F-150 equipped with a 2.5" inlet and outlet. Sold individually.
