More Horsepower. Gain more power potential under the hood of your Sierra 1500 when you upgrade to the Flowmaster Super 50 Series 2.5 in. Offset/Center Oval Muffler. Replacing your stock muffler with this stainless steel low-resonance one can improve not only fuel economy but also level up your rig's horsepower and torque.
Mild to Stock Tone. Flowmaster's Super 50 Series Oval Muffler has a mild exterior exhaust tone that is deeper and more welcoming than the stock. With a minimal internal drone, the muffler enables you and your passengers to talk without being drowned out by its noise.
409S Stainless Steel. This Super 50 Oval Muffler is crafted from tough 16-gauge 409S stainless steel and is fully WIG welded for high durability. The black case measuring 17 in. x 10 in. x 5 in. is larger than Flowmaster's 50 Series Delta Flow Muffler and has a 2.5 in. offset inlet with a 2.5 in. center outlet.
Modifications Required. This Muffler was designed to be used on mutliple applications, as it is not a direct fit replacement part. In order to install this Muffler properly on your vehicle, some modifications to the exhaust system will be required.
Application. Flowmaster's Super 50 Series 2.5 in. Offset/Center Oval Muffler is made to fit all 1999-2024 GMC Sierra 1500 models.
