Description
Performance Muffler. The Flowmaster Super HP-2 18-Inch Center/Center Oval Muffler; 2.50-Inch Inlet/2.50-Inch Outlet; 409 Stainless is engineered to enhance exhaust flow while delivering a moderate sound level. It improves vehicle performance by reducing backpressure and maintaining a controlled exhaust tone, making it ideal for street and mild performance applications.
Construction and Appearance. Built with durable 409 stainless steel, this muffler features a compact oval body and a sleek black high-temperature paint finish. Its laminar flow technology reduces turbulence inside the muffler for optimized exhaust gas flow and enhanced durability.
Installation. Installation requires moderate skill with slip-fit inlet and outlet connections suitable for clamp-on or weld-on applications. Its universal fit design may require some adaptation, but no specialized drilling is typically necessary.
Warranty. This muffler includes a lifetime limited warranty, providing long-term performance and quality assurance.
Application. Designed to fit universal exhaust systems for a wide range of vehicle types including 4- and 6-cylinder engines, classic and late model muscle cars, street rods, street/strip, and trucks/SUVs. Some adaptation may be necessary for proper fitment.
