Performance Boost. Reinforce your Sierra’s exhaust sound and engine power by adding the GMS Manual 2.50-Inch Exhaust Cutouts. GMS engineered this pair of manually-operated exhaust valves to open and close by means of the 3-bolt block-off plates. It gives you the ability to switch from a refined, confident exhaust sound to a more powerful and aggressive growl that accompanies the intensified exhaust flow.
Long-Lasting Functionality. GMS crafted these Manual Exhaust Cutouts using premium, 2.50-inch tubing made of high-strength aluminized steel. This construction exhibits excellent structural integrity and high corrosion resistance to handle high-temperature environments and the corrosive attacks from the exhaust gases. The heavy-duty flange, block-off plates, and band clamps ensure tight seals and secure mounting.
Bolt-On Installation. This pair of Manual Exhaust Cutouts directly welds on to your Sierra’s exhaust system.
Limited Warranty. A 90-day limited warranty that covers manufacturing defects in materials and craftsmanship is offered by GMS for these Manual Exhaust Cutouts. Some exclusions apply; please check the full warranty policy for complete details.
Application. The GMS Manual 2.50-Inch Exhaust Cutouts are intended for use on all 1999-2025 GMC Sierra 1500 models.
