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!

Monster Performance And Modes price. Improves airflow up to 122 percent. Banks new Monster Sport Exhaust is one cool cat back system! And its low price. Thats way cool. The system slashes backpressure; increases exhaust flow; improves fuel economy and delivers extra power to your rear wheels. Exhaust tip optional.
