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!\u003c\/p\u003e\u003cp\u003ePolished-stainless steel with heatshield 2.5 inch inlet x 3.5 inch outlet\u003c\/p\u003e","brand":"Banks Power","offers":[{"title":"Default Title","offer_id":51776147063096,"sku":"B003 52410","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-94223-4706012-square.webp?v=1779469342","url":"https:\/\/store.motormia.co\/products\/banks-power-gm-454-mh-efi-vortec-w-heatshield-muffler-2-2-5in-x-3-5in-s-s","provider":"MOTORMIA","version":"1.0","type":"link"}
