Exclusive expansion chamber dissipates annoying mid-range drone. Flows up to 201% better than stock. Authoritative, but never overpowering, exhaust sound. Polished-stainless steel. 3.5 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. 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":44328316764379,"sku":"GBE52428","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/8809\/8779\/products\/0e142c006651508b2c80c02628d83b04.jpg?v=1697411953","url":"https:\/\/www.functionwerks.com\/products\/banks-power-98-04-ford-5-4-6-8l-truck-muffler-3-5in-x-3-5in-s-s","provider":"FunctionWerks","version":"1.0","type":"link"}
