      Description

      Superior Exhaust Cutouts. Give your 1999-2025 Sierra a deep and loud exhaust note that can be hushed with the flip of a switch with a Granatelli Motor Sports 4" Electronic Exhaust Cutout System. GMS Electronic Exhaust cutouts standout from other cutouts thanks to their incredible craftsmanship and one touch functionality that allows you to open and close the exhaust cutouts with one simple flick of a switch. Completed with a set of polished stainless steel turndowns that point the exhaust away from your truck at a 45 degree angle, GMS Exhaust Cutouts make your Sierra sound the way it should from the factory, while still allowing you quiet operation when needed.

      Industry Leading Quality. Designed to endure the high temperatures of your GMC Sierra's exhaust system, GMS 4' Electronic Exhaust Cutouts are crafted from 6061 aircraft quality aluminum that won't warp from heat or fail over prolonged use. The carbon steel drive gears are able to withstand incredible hot temperatures; while the high torque DC gear reduction driven motor enables totally open and closed operation every time.

      Custom Installation. A GMS 4" Electronic Exhaust Cutout System is the perfect addition to any custom exhaust system and can be easily added to your Sierra. With all of the necessary hardware and gaskets included along with the appropriate wiring harness, the exhaust cutout system can be welded on up to any 4" exhaust system in a couple of hours. The hardest part of the install will be running the wiring into the cabin for the one touch switch.

      Application. The Granatellii Motor Sports 4" Electronic Exhaust Cutout System is compatible with all 1999-2025 GMC Sierra pickup trucks, working on any 4" exhaust system.
