{"product_id":"evolution-line-titanium-exhaust-system-22","title":"Evolution Line Titanium Exhaust System","description":"The Akrapovic Evolution Line (Titanium) exhaust system is engineered for the BMW M440i (G22, G23), offering a substantial upgrade in sound and performance. Constructed from high-grade, lightweight titanium, it is finished with distinctive carbon-fibre tailpipes and a durable austenitic stainless-steel link pipe set. This system boasts two valves, one more than the stock configuration, and comes with a TNG controller to manage the additional exhaust valve, allowing for tailored sound profiles. Two specially tuned resonators are integrated to produce a deep, rich, and sporty exhaust note, carefully balanced to avoid any drone or unwanted resonance, complementing the straight-six engine's character.\n\nPerformance figures from Akrapovic's dyno testing show gains of 8.7 kW (11.8 hp) at 5,600 rpm and a torque increase of 17.1 Nm at 4,100 rpm compared to the stock exhaust. The system also achieves a significant weight reduction of 23% over the original component. Special parts for intricate construction are cast in Akrapovic's in-house foundry.\n\nFitment requires an extra stock valve actuator (part #18308686640) for installation on BMW M340i (G20, G21) and M440i (G22, G23, G26) models. The Evolution Line (Titanium) is exclusively for non-OPF (Otto Particulate Filter) vehicles; the ECE type approval certificate is not valid for these non-OPF applications.\n\nIMPORTANT NOTE: This product is intended for track or off-road use only and does not meet emission compliance requirements for street or highway use. Installation or use on a public road vehicle is a violation of the Clean Air Act. Remapping of the ECU is recommended.","brand":"MODE Auto Concepts","offers":[{"title":"Default Title","offer_id":52872250884408,"sku":"akrapovic-bmw-g22-g23-m440i-slip-on-line-titanium-opf-gpf-back-exhaust","price":299.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/evolution-line-titanium-exhaust-system-22","provider":"MOTORMIA","version":"1.0","type":"link"}
