Rather than simply adapting a universal muffler design, Eisenmann engineered every component of the system specifically for the G8X chassis and S58 powerplant. Each exhaust system is constructed from high-grade 304 stainless steel with carefully optimized wall thickness throughout to achieve the ideal balance between weight reduction, durability, and acoustic performance.\u003c\/p\u003e \u003cp\u003eThe muffler canisters are machine-pressed using a series of deep-draw dies unique to Eisenmann, creating exceptional canister rigidity while contributing to the company’s signature exhaust tone. The canister shape was specifically engineered to eliminate visibility from the rear view of the vehicle, significantly improving the appearance of the G8X rear diffuser area.\u003c\/p\u003e \u003cp\u003eInternally, multiple airflow paths work seamlessly with BMW’s factory Comfort, Sport, and Sport Plus drive modes, allowing the integrated valve control system to dramatically alter the exhaust character depending on driving conditions. During relaxed cruising, the system maintains a refined and controlled tone, while aggressive throttle input transforms the S58 into a deep and aggressive soundtrack.\u003c\/p\u003e \u003cp\u003eThe Eisenmann Heritage exhaust system is available as either a rear section or complete exhaust system, allowing owners to tailor the system to their desired sound level and future modification plans.\u003c\/p\u003e \u003cp\u003eEisenmann’s massive 110mm LeMans-style tips feature a unique side cut-out design showcasing the Eisenmann signature logo. An optional Black Series finish is also available, featuring a high-temperature ceramic coating engineered to improve heat dissipation and corrosion resistance.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDesigned for the BMW G8X M3 and M4\u003c\/li\u003e \u003cli\u003eRetains factory electronic valve control\u003c\/li\u003e \u003cli\u003eAvailable as rear section or complete exhaust system\u003c\/li\u003e \u003cli\u003eHandmade in Germany\u003c\/li\u003e \u003cli\u003eConstructed from 100% stainless steel\u003c\/li\u003e \u003cli\u003eEngineered specifically for the BMW S58 platform\u003c\/li\u003e \u003cli\u003eEisenmann 110mm LeMans-style exhaust tips\u003c\/li\u003e \u003cli\u003eOptional Black Series ceramic coating available\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eBMW M3 (G80 \/ G81)\u003c\/li\u003e \u003cli\u003eBMW M4 (G82 \/ G83)\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eProfessional installation is recommended\u003c\/li\u003e \u003c\/ul\u003e","brand":"Eisenmann","offers":[{"title":"4x110mm Side-Cut Silver LeMans Tips","offer_id":67981475152026,"sku":"B5470.01104.31","price":4595.0,"currency_code":"USD","in_stock":true},{"title":"4x110mm Side-Cut Black LeMans Tips","offer_id":67981475184794,"sku":"B5470.01104.32","price":4595.0,"currency_code":"USD","in_stock":true},{"title":"4x110mm Side-Cut Carbon LeMans Tips","offer_id":67981475217562,"sku":"B5470.01104.CSS","price":5265.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/7569\/3466\/files\/51370692558_a4e57f25b4_b.jpg?v=1793133812","url":"https:\/\/apexmotorsportswa.com\/products\/eisenmann-g8x-m3-m4-performance-exhaust-system-valved","provider":"Apex Motorsport","version":"1.0","type":"link"}
