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.\n\u003cbr\u003eMonster 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!\n\u003cbr\u003eExhaust Muffler, Stainless Steel, 4 inch Inlet and Outlet\u003c\/p\u003e\n\n\u003cp\u003eAir Freight Prohibited: false\n\u003cbr\u003eNot Carb Approved: false\n\u003cbr\u003eLtl Freight Required: false\n\u003cbr\u003eProp 65: Y\n\u003cbr\u003ePart Type: automotive\n\u003cbr\u003eEpa: N\/A\n\u003cbr\u003eCarb Acknowledgement Required: false\u003c\/p\u003e","brand":"Banks Power","offers":[{"title":"Default Title","offer_id":50172976660800,"sku":"4381138","price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0835\/8585\/9904\/files\/4551c3b6821b6fd12fbe8411ba3a4688.jpg?v=1737165727","url":"https:\/\/spikesspeed.us\/products\/banks-power-various-applications-muffler-4in-x-4in-s-s","provider":"Spikes Speed Shop Inc","version":"1.0","type":"link"}
