      Description

      Unrestricted Sound. Set your Sierra free from its restrictive factory muffler with the Magnaflow Direct-Fit Replacement Muffler. This kit contains a muffler delete pipe that enables you to have a completely unrestricted exhaust flow going. As a result, you’ll have a louder and deeper engine tone that’s not obnoxious for the neighbors.

      Added Performance Gains. This replacement muffler kit is not just for engine sound though. You can also expect a slight bump of horsepower and torque with the decrease in backpressure.

      Tough Stainless Steel Build. The muffler delete pipe and its accompanying clamps are made entirely of high-quality 409-grade stainless steel.

      Easy Installation. The beauty of this Magnaflow Direct-Fit Replacement Muffler is that you don’t have to overhaul your entire exhaust system to get the sound and boost in performance you want. That said, you might need to cut the welded factory muffler out before you can insert this delete pipe.

      Limited Lifetime Warranty. Magnaflow warrants the Magnaflow Direct-Fit Replacement Muffler to be free from materials and workmanship defects as long as it is installed on the original vehicle. For more information, please contact customer service.

      Application. The Magnaflow Direct-Fit Replacement Muffler will fit all 2019-2025 GMC Sierra 1500 4.3L models.

          Word on the Trail

          I'm a new & reluctant customer. So I contacted by phone & chat with several different questions about a product I needed to order. They were very knowledgeable about the product. I was given nothing less than the most professional assistance EVER, both times. I WILL be a returning customer.
