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.

Banks utilizes durable ceramic packing with a high temp rating so it won't degrade like fiberglass.\u003c\/p\u003e\n\u003cp\u003eAdd 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\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSuperior Flow and Rich, Throaty Sound\u003c\/li\u003e\n\u003cli\u003eStraight-through flow path\u003c\/li\u003e\n\u003cli\u003eExclusive expansion chamber dissipates annoying mid-range drone\u003c\/li\u003e\n\u003cli\u003eFlows up to 201 percent better than stock\u003c\/li\u003e\n\u003cli\u003eAuthoritative, but never overpowering, exhaust sound\u003c\/li\u003e\n\u003cli\u003ePolished-stainless steel\u003c\/li\u003e\n\u003cli\u003e4 inch diameter in\/out\u003c\/li\u003e\n\u003c\/ul\u003e\n\n","brand":"Banks Power","offers":[{"title":"Default Title","offer_id":47280205922442,"sku":"BANKS-53509","price":319.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/0619\/2778\/files\/0_cc0f38ee2d3f532fd314c2e3d943c3cd_normalized.jpg?v=1776243505","url":"https:\/\/www.onlyinstock.com\/products\/banks-power-53509","provider":"Only In Stock","version":"1.0","type":"link"}
