      Unrestricted Exhaust Note. Allow your 1999-2021 Silverado to go from quiet and restrained to loud and unrestricted with the press of a button on the GMS 2.5" Electronic Exhaust Cutout. Freeing up 10-15 HP, the 2.5" GMS exhaust cutout allows you to control how loud your exhaust is at any given time. Opening up the exhaust under the cabin will make your Silverado a lot louder and more throaty.

      Aircraft Grade Aluminum. Granatelli Motor Sports use one of the highest quality materials like CNC machined 6061 aircraft aluminum on this exhaust cutout. Stainless Steel butterfly plates and blade shafts open and close the cutout, while polished stainless steel turndowns channel the noise out and away, with a clean look. High temperature carbon steel drive gears power the cutout, with a high torque DC gear reduction driven motor provides a total open and close of the cutout.

      Bolt-On Installation. The GMS 2.5" Electronic Exhaust Cutout offers a fairly straightforward installation, however it would help to have some prior experience before wrenching. All of the hardware, gaskets, and wiring are included to provide you with the necessary components you need to complete this installation in an afternoon.

      Application. The 2.5" GMS Electronic Exhaust Cutout is compatible with all 1999-2021 Chevrolet Silverado 1500 pickup trucks.
