Power and Versatility. GMS offers the Manual 3-Inch Exhaust Cut-Outs to give your Sierra 1500 a high-quality OEM sound for street use with the ability to generate a commanding growl when needed. These manually-operated exhaust valves can be opened and closed by removing the 3-bolt block-off plates underneath your truck. Installing this pair of exhaust cutouts on your Sierra will improve your engine power by enhancing the exhaust flow for bolder outdoor confidence.
Premium Construction. These Manual Exhaust Cutouts were engineered using high-quality, 3-inch aluminized steel tubing with exceptional durability and excellent structural properties. This material is also highly corrosion-resistant, can withstand the chemical attacks from the exhaust gases, and survives other physical impacts. Moreover, the package also comes with heavy-duty block-off plates and durable band clamps for stable mounting and leak-free operations.
Bolt-On Installation. Designed for a direct-fit upgrade, this pair of Manual Exhaust Cutouts attaches to the factory mounting locations on your Sierra’s exhaust system. The straightforward installation process completes with light to moderate mechanical skills required.
Limited Warranty. These Manual Exhaust Cutouts are backed by a 90-day limited warranty that covers manufacturing defects in materials and craftsmanship. The warranty is considered void if the product shows signs of alteration, negligence, or misuse. Please read the full warranty policy for the other limitations and exclusions.
