Banks Power 99-03 Ford 7.3L Muffler Kit - 4in X 4in S/S

Monster Exhaust Benefits. Replacing the restrictive stock muffler with Banks free-flowing Monster muffler makes a huge difference in airflow, sound, and performance. The Banks muffler has a large inlet and outlet where the exhaust flows straight through, compared to the torturous stock design with hairpin chambers that build up back-pressure. Only Banks Monster Muffler has an expansion chamber to alleviate the nasty drone that other straight-through mufflers are known for. Banks utilizes durable ceramic packing with a high temp rating so it won't degrade like fiberglass. Add it all together and you get a muffler that flows over three times better than stock and delivers a pleasing, throaty rumble!d 7.3L Key Features: Superior Flow and Rich, Throaty Sound Straight-through flow path Exclusive expansion chamber dissipates annoying mid-range drone Flows up to 201 percent better than stock Authoritative, but never overpowering, exhaust sound Polished-stainless steel 4 inch diameter in/out CARB E.O.
