      Raw Exhaust Noise. Let your Silverado's exhaust roar to life with Granatelli Motor Sports Electronic Exhaust Cutouts. 3" in diameter, these GMS Silverado Exhaust Cutouts go from being mild-mannered to wild and unrestricted with the toggle of a switch. An internal processor and "smart chip" automatically fully opens and closes the exhaust cutout when you press the switch, providing longevity from the cutout and easy-to-use performance. When open, the GMS 3" Electronic Exhaust Cutouts can add up to 10-15 HP to your Silverado, while delivering an intimidating exhaust note.

      Durable Aluminum Construction. GMS Electronic Exhaust Cutouts are designed with quality in mind and are crafted from strong and lightweight 6061 Aircraft grade aluminum. High-temperature long lasting steel gears are used to operate the cutouts, withstanding high heat from the exhaust gases coming out of your truck. The high-torque DC gear-driven motor ensures that the exhaust flaps open and close every time you hit the switch, giving you performance you can depend on.

      Straightforward Installation. Installing GMS' Electronic Exhaust Cutouts can take about 2-3 hours with a set of hand tools. These are a great replacement option and will work with other GMS exhaust components.

      Application. The 3" GMS Electronic Exhaust Cutout is specifically designed to fit on all 1999-2020 Chevy Silverado 1500's.

      Technical Note. These are just the cutouts and nothing else. In order to make these cutouts work you will also need the y-pipe splitter, the turndowns, and other necessary hardware.
