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!","brand":"Banks Power","offers":[{"title":"Default Title","offer_id":48082516017397,"sku":"GBE52410","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0315\/9146\/5019\/files\/90896f5c39b9cdda44770b95f5f4be8e.jpg?v=1777551817","url":"https:\/\/www.ravperformance.com\/products\/banks-power-gm-454-mh-efi-vortec-w-heatshield-muffler-2-2-5in-x-3-5in-s-s","provider":"RAV Performance","version":"1.0","type":"link"}
