Offered in Sport sound level with 2 x 90mm or 4 x 76mm tips, the system delivers a deeper, more refined note from the N55 turbocharged inline-six while maintaining OEM-quality fitment. Rear bumper modification is required with the 4 x 76mm tip style.\u003c\/p\u003e\n\u003cp\u003eEisenmann has supplied OEM exhaust systems to Porsche and AMG for decades. That engineering heritage is reflected in the tolerances, finish quality, and sound character of every Eisenmann performance exhaust, each one hand-built in Germany from mandrel-bent T304 stainless steel with TIG-welded construction. The Sport tune delivers a refined daily-driver tone with Eisenmann's trademark character: a deep sound at low RPM building to a true performance note at high RPM on the BMW F20 M135i.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eProduct Details\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Eisenmann\u003c\/li\u003e\n\u003cli\u003eMaterial: T304 stainless steel\u003c\/li\u003e\n\u003cli\u003eConstruction: Mandrel-bent, hand-TIG-welded in Germany\u003c\/li\u003e\n\u003cli\u003eTip Styles: 2 x 90mm, 4 x 76mm\u003c\/li\u003e\n\u003cli\u003eSound Level: Sport\u003c\/li\u003e\n\u003cli\u003eNote: Rear bumper modification required with 4 x 76mm tips\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eAvailable Configurations\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2 x 90mm - SKU: B5432.00902 - $2,300.50\u003c\/li\u003e\n\u003cli\u003e4 x 76mm - SKU: B5450.00762 - $2,628.40\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eVehicle Applications\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBMW F20 M135i\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Eisenmann","offers":[{"title":"2 x 90mm","offer_id":51715906371830,"sku":"B5432.00902","price":2300.5,"currency_code":"USD","in_stock":true},{"title":"4 x 76mm","offer_id":51715906404598,"sku":"B5450.00762","price":2628.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/31499186592_9a6c0e96ca_h_79572442-d33c-482b-bef5-0467613dcba2.jpg?v=1790000605","url":"https:\/\/autotecknic.com\/products\/eisenmann-f20-m135i-performance-exhaust","provider":"AutoTecknic USA","version":"1.0","type":"link"}
