Description
The MWA (Muffler With Attitude) is Gibson’s loudest, freest-flowing Superflow muffler. Its straight-through design flows almost as well as an open 3 in. pipe, while the low-profile oval case helps keep cabin drone down, which makes it a favorite for trucks, hot rods and off-road builds.

- 3 in. center inlet and 3 in. center outlet; non-directional
- Straight-through core with no packing or baffles to wear out
- Aggressive sound with minimal interior drone
- Stainless steel construction, made in the USA
- Lifetime limited warranty
