      Description

      Performance Muffler. The Flowmaster 80 Series Offset/Offset Same-Side-Out Oval Muffler with 2.50-inch inlet and outlet is designed to deliver a moderate to aggressive exhaust tone. It’s perfect for custom exhaust setups where a side exit in front of the rear tires is preferred, enhancing both sound and style without sacrificing performance.

      _x000D_

      Construction and Appearance. Built from durable 409 stainless steel, this muffler resists corrosion and offers long-lasting service life. Its compact oval shape and high-temperature black paint finish improve both durability and vehicle appearance.

      _x000D_

      Installation. Installation requires slip-fit connection with clamp-on or weld-on inlet and outlet options. Some adaptation may be necessary due to the universal fitment design, but no extensive drilling is typically needed.

      _x000D_

      Warranty. Backed by a lifetime limited warranty against manufacturing defects for the life of the product.

      _x000D_

      Application. Fits universal applications; some adaptation may be required to suit specific vehicle configurations and fitments.
