      Quality Materials. Stainless Works' Turbo Chambered Cat-Back Exhaust System with Dual Split Rear Exits is built from superior T304 stainless steel for your GMC Sierra. This is the same steel that's used in aeronautic applications. Attaching to factory connections beyond the catalytic converter, the exhaust system's 3-inch, mandrel-bent tubing provides additional power and better gas mileage due to improved spent gas management. Dual exhaust pipes exit in the rear and are topped off with 4-inch rolled slash cut polished tips.

      Covered for Life.
      Stainless Works covers the Turbo Chambered Cat-Back Exhaust System with a limited lifetime warranty. Your new exhaust system is covered if rust, corrosion, or defects in workmanship occur under normal use for as long as you own your Silverado or Sierra.

      Direct Fit Upgrade.
      Stainless Works designed their Cat-Back to be installed with your Factory Exhaust Manifolds. There is no cutting or extra modifications required. Installation of this Stainless Works Exhaust can be completed in about a two hours with just basic hand tools.
