Description
Unleash Your Sierra's Missing Growl. If you're looking to squeeze some more noise out of your Sierra, consider swapping the muffler with a performance-inspired replacement, such as this Magnaflow 3.50-Inch Round Glasspack Performance Muffler. This muffler features a classic glasspack design with straight-through routing and minimal packing, producing a deep, aggressive growl fit for a heavy-duty pickup.
Enhanced Performance. With its straight-through design, this muffler cuts down on the backpressure of the factory exhaust system and increases flow. As a result, you’ll enjoy more power and better fuel economy.
Classic Appearance. The Magnaflow Glasspack is a blast from the past, featuring the classic glasspack styling popularized by hot-rodders in the 60s and 70s. This muffler features a long and narrow form factor and bright red corrosion-resistant coating, guarding the underlying alloy against rust and oxidation.
Warranty. A limited 90-day warranty covers this product against manufacturing defects.
Application. This Magnaflow 3.50-Inch Round Glasspack Performance Muffler fits all 2020-2024 GMC Sierra 2500s.
