Description
Performance Muffler. The Flowmaster Super HP-2 18-Inch Center/Center Oval Muffler features a 2-inch inlet and outlet constructed from durable 409 stainless steel. It delivers a balanced, moderate sound ideal for street and performance vehicles. Utilizing laminar flow technology, this muffler improves exhaust flow and enhances engine performance, making it a reliable choice for automotive enthusiasts seeking quality muffling without excessive noise.
Construction and Appearance. Constructed from 409 stainless steel, this muffler has a compact oval design finished with high-temperature black paint to resist corrosion and heat. Its laminar flow core is enclosed in a sleek, square case, ensuring robust durability and a modern aesthetic appeal.
Installation. Installation is straightforward with slip-fit inlet and outlet connections designed for clamp-on or weld-on applications. Some adaptation may be necessary, as this is a universal muffler and not intended as a direct bolt-on fit.
Warranty. This muffler is backed by a lifetime limited warranty, providing long-term assurance of its build quality and performance. Application. Fits universal vehicles, including 4- and 6-cylinder engines, classic and late model muscle cars, street rods, street/strip vehicles, and trucks/SUVs, with some adaptation required for proper fitment.
