    Unrestricted Exhaust Flow. Unleash your Sierra's exhaust with Granatelli Motor Sports' 2.5" Electronic Exhaust Cutout System. The one touch operation of the GMS 2.5" Electronic Exhaust Cutout allows you to easily open up the cutout or close it, giving your Sierra a loud and raspy exhaust note or a quiet and inconspicuous exhaust note. The included V-Band Clamps provide a tight and precise fitment that allows the polished stainless steel turndown to be rotated 360 degrees.

    Heat Resistant Construction. GMS 2.5" Electronic Exhaust Cutouts are crafted from aircraft grade 6061 aluminum and use an assortment of stainless steel parts, such as the butterfly plates, Y-pipe, blade shafts, and turndowns. High temperature carbon steel drive gears power the cutout and high torque DC gear reduction motors with a totally closed operation.

    Custom Fit. Installing 2.5" GMS Electronic Exhaust Cutouts is straightforward, but will take a little bit of time. The fit on the cutouts is smooth and clean, making for a quick install with the use of the included flanges and clamps. The tricky part of the job is feeding the wiring for the electronic cutout into your cabin. With a set of instructions and the proper tools, anyone can knock this mod out in an afternoon.

    Application. GMS 2.5" Electronic Exhaust Cutouts can be installed on any vehicle with a 2.5" exhaust system, including your 2007-2019 GMC Sierra 1500.
