      Description

      Give Your Sierra a Tough, Aggressive Exhaust Note. Most modern automotive manufacturers, including GM, engineer extremely quiet exhaust systems for their light-duty vehicles, like your Sierra. These systems feature oversized resonators, mufflers, and small diameter piping, reducing efficiency and muffling the glorious sounds from your pickup’s Vortec V8. While some enjoy the quiet, most enthusiasts love a deep, satisfying rumble whenever they put their foot on the gas. One of the most recognizable exhaust notes can be had from installing a premium Flowmaster muffler, like this Original 40 Series Offset/Center Oval Muffler. This product produces the trademark Flowmaster sound, unleashing your Sierra’s V8 engine for an improved exhaust note and additional power. 

      Improved Performance. Your Sierra’s factory exhaust system is known to rob power from the drivetrain, smothering the engine and reducing the amount of air that can escape through the tailpipe. This restriction directly reduces the air entering the engine, thus limiting power. This Flowmaster muffler does an excellent job of uncorking some of those lost ponies, featuring a high-flow design with minimal baffling and restriction. 

      Premium Construction. This muffler is manufactured from heavy-duty aluminized steel for excellent strength and corrosion resistance. It also features a durable black coating for an unobtrusive appearance and additional protection from the elements. 

      Warranty. A limited 3-year warranty covers this product against manufacturing defects. 

      Application. This Flowmaster Original 40-Series Offset/Center Oval Muffler features a universal fitment.
