Banks Power 99-03 Ford 7.3L Muffler Kit - 4in X 4in S/S 53509

Banks Power Muffler 53509 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. And in between, the exhaust flows straight through, instead of torturously winding its way back and forth inside hairpin chambers and building up back-pressure. And 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! Muffler Kit; 4in. X 4in.
