Performance Exhausts

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 wont 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!

It's all about the flow when you install Banks Power Dynaflow mufflers. Massive outlets, instead of the small torturous chambers of your stock muffler, provide more internal flow area to reduce backpressure. Unlike your factory models, they're also resonance-tuned to dampen annoying tones. Airflow restrictions waste power, too! So, here's your exhaust flow solution--Banks Power Dynaflow mufflers offer an exhaust sound that is authoritative, yet civilized, without excessive restriction and with increased performance.
