{"product_id":"eisenmann-g8x-m3-m4-performance-exhaust-system-valved","title":"Eisenmann G8X M3 \/ M4 Performance Exhaust System - Valved","description":"\u003cp\u003eThe Eisenmann G8X M3 \/ M4 Performance Exhaust System - Valved was developed with the same obsessive attention to detail that defines BMW M’s latest generation of high-performance vehicles. From the moment the G8X M3 and M4 platforms were introduced, it became clear that BMW approached every aspect of the chassis, drivetrain, and driving experience with uncompromising engineering precision. Eisenmann responded with the same philosophy, developing an exhaust system that would complement the G8X platform at the highest possible level.\u003c\/p\u003e\n\n\u003cp\u003eRather 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 the system to achieve the ideal balance between weight reduction, durability, and acoustic performance.\u003c\/p\u003e\n\n\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 visual appearance of the G8X rear diffuser area.\u003c\/p\u003e\n\n\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 worthy of BMW M’s flagship performance sedan and coupe platforms.\u003c\/p\u003e\n\n\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. The complete system replaces everything from the exhaust tips rearward from the factory downpipes, creating a true bolt-on solution with improved flow capacity and reduced restriction for higher-performance applications.\u003c\/p\u003e\n\n\u003cp\u003eFor enthusiasts seeking additional visual distinction, Eisenmann’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 while delivering a stealth-inspired appearance.\u003c\/p\u003e\n\n\u003cp\u003eEisenmann has been handcrafting exhaust systems in Germany for over 30 years and serves as an OE supplier to some of the world’s leading automotive manufacturers. That experience is reflected in the quality, sound, and finish of every Eisenmann performance exhaust system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for the BMW G8X M3 and M4\u003c\/li\u003e\n\u003cli\u003eRetains factory electronic valve control\u003c\/li\u003e\n\u003cli\u003eAvailable as rear section or complete exhaust system\u003c\/li\u003e\n\u003cli\u003eHandmade in Germany\u003c\/li\u003e\n\u003cli\u003eConstructed from 100% stainless steel\u003c\/li\u003e\n\u003cli\u003eEngineered specifically for the BMW S58 platform\u003c\/li\u003e\n\u003cli\u003eAvailable with Eisenmann 110mm LeMans-style exhaust tips\u003c\/li\u003e\n\u003cli\u003eOptional Black Series ceramic coating available\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m3-g80\"\u003eBMW M3 (G80 \/ G81)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m4-g82-g83\"\u003eBMW M4 (G82 \/ G83)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eAvailable Configurations\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSKU: B5470.01104.31 - G8X M3\/M4 Performance Exhaust System - Valved\u003c\/li\u003e\n\u003cli\u003eSKU: B5470.01104.32 - G8X M3\/M4 Performance Exhaust System - Valved\u003c\/li\u003e\n\u003cli\u003eSKU: B5470.01104.CSS - G8X M3\/M4 Performance Exhaust System - Valved\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eRelated Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/products\/eisenmann-g8x-m3-m4-center-pipe-set?pr_prod_strat=pinned\u0026amp;pr_rec_id=3cd25a90c\u0026amp;pr_rec_pid=7243321835716\u0026amp;pr_ref_pid=7277489815748\u0026amp;pr_seq=uniform\"\u003eEisenmann G8X M3 \/ M4 Center Pipe Set\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProfessional installation is recommended\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/pages\/faq#faq-emissions-notice\" target=\"_blank\"\u003eView emissions compliance notice\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Eisenmann","offers":[{"title":"4x110mm Side-Cut Silver LeMans Tips","offer_id":51457475870884,"sku":"B5470.01104.31","price":6570.85,"currency_code":"CAD","in_stock":true},{"title":"4x110mm Side-Cut Black LeMans Tips","offer_id":51457475903652,"sku":"B5470.01104.32","price":6570.85,"currency_code":"CAD","in_stock":true},{"title":"4x110mm Side-Cut Carbon LeMans Tips","offer_id":51457475936420,"sku":"B5470.01104.CSS","price":7528.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0013\/9929\/1964\/files\/51370692558_a4e57f25b4_b.jpg?v=1787779548","url":"https:\/\/www.amtuning.ca\/products\/eisenmann-g8x-m3-m4-performance-exhaust-system-valved","provider":"AM Tuning Canada","version":"1.0","type":"link"}
