Description
Performance Muffler. The Flowmaster 80 Series Offset/Offset Same-Side-Out Oval Muffler; 2.50-Inch Inlet/2.50-Inch Outlet is designed to deliver a moderate to aggressive exhaust tone, enhancing the sound profile of muscle cars and street/strip vehicles. It optimizes exhaust flow in custom applications where side exit in front of the rear tires is preferred, balancing sound and performance.
Construction and Appearance. This muffler features durable 409 stainless steel construction with a compact 4.0-inch by 9.5-inch by 13.0-inch case, finished in high-temperature black paint for enhanced corrosion resistance and aesthetic appeal. Its oval chambered design provides a classic performance sound with a robust build quality.
Installation. Installation requires a moderate level of mechanical skill and is slip-fit designed for clamp-on or weld-on applications. No drilling is typically necessary, but new hangers are required and not included.
Warranty. This muffler is backed by a lifetime limited warranty against defects in materials and workmanship.
Application. Fits universal applications; some adaptation may be required to ensure proper fitment and alignment, depending on the vehicle setup and custom exhaust configurations.
