Designed specifically for the S55 3.0-liter twin-turbocharged inline-six, the Eisenmann center pipes replace the factory resonators between the catalytic converters and the rear mufflers, improving mid-system exhaust flow and allowing more of the S55's inherent acoustic character to reach the rear of the car. The result is a more engaging and involving exhaust note in combination with the factory or an aftermarket cat-back exhaust.\u003c\/p\u003e\n\n\u003cp\u003eConstructed from 304 stainless steel and handcrafted in Germany, the set is available in non-resonated and resonated configurations. The non-resonated version removes the factory resonators entirely for maximum flow improvement and sound enhancement, delivering a notably more aggressive and direct exhaust note from the S55. The resonated option provides a more moderate enhancement that retains some acoustic management for a refined result while still offering a clear improvement over the factory setup. Both configurations use direct factory mounting points for a clean installation with no modifications required.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eFitment\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBMW F80 M3 (S55 3.0L Twin-Turbo, 2015-2018)\u003c\/li\u003e\n  \u003cli\u003eBMW F82 M4 Coupe, F83 M4 Convertible (S55 3.0L Twin-Turbo, 2015-2020)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMaterial: 304 stainless steel\u003c\/li\u003e\n  \u003cli\u003eConfigurations: Non-Resonated, Resonated\u003c\/li\u003e\n  \u003cli\u003eHandcrafted in Germany by Eisenmann\u003c\/li\u003e\n  \u003cli\u003ePart numbers: B8888.00000 (Non-Resonated), B8888.00001 (Resonated)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Eisenmann","offers":[{"title":"Non Resonated (B8888.00000)","offer_id":51689097068790,"sku":"B8888.00000","price":2090.0,"currency_code":"USD","in_stock":true},{"title":"Resonated (B8888.00001)","offer_id":51689097101558,"sku":"B8888.00001","price":2487.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/15386104063_e06a24a421_b_51d1bf64-902e-48be-9023-0ffc55ed05b4.jpg?v=1789735660","url":"https:\/\/autotecknic.com\/products\/eisenmann-f8x-m3-m4-centerpipes","provider":"AutoTecknic USA","version":"1.0","type":"link"}
