      Louder Made Easy. With just the press of a button you can open up your exhaust and hear it rumble with the 2.5" GMS Electronic Exhaust Cutout System. Using stainless steel butterfly plates, these electronic exhaust cutouts can be opened with the press of a button thanks to "smart chip" controlled motors. GMS Electronic Silverado Exhaust Cutouts will add a much deeper, louder, and more aggressive exhaust tone to your Silverado.

      Strong Construction. GMS 2.5" Silverado Exhaust Cutouts are crafted from aircraft grade CNC 6061 aluminum that is built to withstand prolonged use. The cutouts are powered by high torque DC gear reduction motors ensuring total open and closed operation every time you hit the switch. The drive gears are made from high temperature carbon steel that is designed to hold up to high heat from your exhaust system.

      Bolt-On Performance. GMS Electronic Exhaust Cutouts are designed to weld-on right into your Silverado's exhaust system with some minor adjustments to the exhaust system. Provided V-Band clamps help to ensure a snug and secure fit, a necessity for avoiding exhaust leaks.

      Application. GMS 2.5" Electronic Exhaust Cutouts fit on all 1999-2021 Chevrolet Silverado 1500 Pickup Trucks.
