Exclusive expansion chamber dissipates annoying mid-range drone. Flows up to 201% better than stock. Authoritative, but never overpowering, exhaust sound. Polished-stainless steel. 4 inch diameter in\/out.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 where the exhaust flows straight through, compared to the torturous stock design with hairpin chambers that build up back-pressure. 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":44328318468315,"sku":"GBE53509","price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/8809\/8779\/products\/cc0f38ee2d3f532fd314c2e3d943c3cd.jpg?v=1697412053","url":"https:\/\/www.functionwerks.com\/products\/banks-power-99-03-ford-7-3l-muffler-kit-4in-x-4in-s-s","provider":"FunctionWerks","version":"1.0","type":"link"}
