Monster Exhaust Benefits. Replacing the restrictive stock muffler with Bank's 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 utilize durable ceramic packing with a high temp rating so it won't degrade like fibreglass. Add it all together and you get a muffler that flows over three times better than stock and delivers a pleasing, throaty rumble!
