      Pitch Perfect. With the mandrel-bent stainless steel piping and a free-flowing muffler design, this signature Magnaflow Street Series Cat-Back Exhaust - Middle Side Exit is a perfect upgrade to your GMC Sierra. The exhaust system delivers the perfect balance between a smooth baritone sound and fierce growl.

      Performance Meets Construction. Stock exhaust systems are restrictive and known to minimize performance. The Magnaflow Street Series Cat-Back Exhaust - Middle Side Exit improves every area of your exhaust system, giving you unfettered exhaust flow, increased horsepower and torque, and better fuel efficiency.

      Resilient Construction. This MagnaFlow Exhaust System is constructed of 409-stainless steel, famous for high thermal stability that withstands bending or deformation as temperatures rise. Every curve and bend is mandrel-bent to ensure the interior surface remains smooth and uninterrupted, continually delivering massive exhaust flow while keeping corrosion at bay.

      Easy Bolt-On Installation. Designed to fit with your Sierra factory housing, the upgrade ships with a manual, instructions and installation hardware.

      Warranty. The exhaust has a lifetime warranty for original buyers.

      Application. Magnaflow Street Series Cat-Back Exhaust – Middle Side Exit fits all 5.3L 2014-2018 GMC Sierras.
