Specially designed to eliminate the high-pitched \"tractor\" rasp of the stock BMW G80 M3 and G82\/G83 M4 exhaust, this single-channel midpipe merges the dual turbo paths into an industry-leading 4.5-inch diameter flow tube. This colossal architecture dramatically lowers the tone of the exhaust, giving your car a vicious, deep, and menacing muscle-car-like rumble. Perfect as an a la carte foundation for a Weekend Warrior setup—keep it subtle with stock rear mufflers or let it scream on demand. CNC mandrel-bent stainless steel ensures precision fitment and maximum clearance.\u003c\/p\u003e","brand":"ARM Motorsports","offers":[{"title":"Default Title","offer_id":42974583226466,"sku":"ARM-G8X-45-SINGLE","price":797.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/4395\/7090\/files\/3V0A0842-2_5000x_4a3472ae-6afa-44e2-9aec-f872cf274ebc.webp?v=1780159536","url":"https:\/\/ortmotorsport.com\/products\/arm-motorsports-4-5-inch-single-midpipe-bmw-g8x","provider":"ORT Motorsport","version":"1.0","type":"link"}
