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\u003ePolished-stainless steel with heatshield 2.5 inch inlet x 3.5 inch outlet\n\u003cbr\u003ePolished-stainless steel with heatshield;2.5 inch inlet x 3.5 inch outlet\n\u003cbr\u003eGM 454 Motorhome EFI (Electronic Fuel Injection) Vortec, with Heatshield\n\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cbr\u003e  \u003cli\u003eDramatically Improves Flow\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\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\n\u003cbr\u003eRegular Stock: false\u003c\/p\u003e","brand":"Banks Power","offers":[{"title":"Default Title","offer_id":48043297210587,"sku":"gbe52410","price":439.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/8559\/1003\/files\/90896f5c39b9cdda44770b95f5f4be8e.jpg?v=1765402795","url":"https:\/\/hnbperformance.com\/products\/banks-power-gm-454-mh-efi-vortec-w-heatshield-muffler-2-2-5in-x-3-5in-s-s","provider":"Hellnback Offroad \u0026 Performance","version":"1.0","type":"link"}
