Maximum Flow, Maximum Sound

The Gibson MWA (Muffler With Attitude) Superflow Oval Muffler is designed for enthusiasts who refuse to compromise on performance. Featuring a true straight-through design, this muffler promotes exhaust gas flow at the highest possible rates, flowing only 3cfm less than a standard 3-inch straight pipe. This ensures your engine achieves its maximum power potential while maintaining a controlled, deep exhaust note.
