DynoMax's after-cat exhaust systems for Mustangs are staples in the exhaust aftermarket. We've had them on numerous cars over the years, including a 347-powered Fox 5.0, and we love the sound. Muffled nicely with the two-cat X-pipe, the DynoMax mufflers have a mild and mellow tone that still has a throaty 5.0-style sound when the gas pedal is tickled. The complete setup includes the tailpipes, mufflers, and mid-pipes that connect the mufflers to the X-pipe. Muffler clamps and hardware are also included.
