      Description

      More Power. Infuse more power into your Sierra 1500 by replacing the stock muffler with Flowmaster's 70 Series 2.5 in. Center/Offset Oval model. This durable WIG-welded muffler uses patented Delta Flow Technology and is designed for more horsepower and torque, as well as improving fuel economy.

      Mellow Exhaust Note. This 70 Series 2.5 in. Center/Offset Muffler uses Flowmaster's Delta Flow Technology to emit a mild external sound so you needn't worry about waking up the neighborhood. With only minimal drone inside the cab, your driving experience can be more enjoyable.

      Rugged Construction. Flowmaster makes this black 70 Series Muffler from strong 16 gauge aluminized steel, and it is fully WIG welded for superior durability. With a 2.5 in. center outlet and 2.5 in offset outlet, the oval muffler with oversized case (22 in. x 10 in. x 5 in.) can deliver more power than stock.

      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. The Flowmaster 70 Series 2.5 in. Center/Offset Oval Muffler is universally designed to fit all 1999-2025 GMC Sierra 1500s.
