This is ahigh-grade lightweight titaniumsystem, finished withhand-crafted carbon-fibre tailpipesand ahigh-grade austenitic stainless-steellink pipe set. Thevalves in each sideare calculated to tailor the sound, andtwo acoustic reflectorsare fitted on the tailpipes to guide the sound into the cars cabin. Because the Akrapovi Evolution Line (Titanium) exhaust system has two valves, one more than the stock configuration, aTNG controller is includedin the product to activate the additional exhaust valve. To make the sound experience even more unique, there aretwo tuned resonators developed especially for this new engine producing a deep, rich, and sporty sound with no unwanted drone or streaming, perfectly aligned with the straight six-cylinder engine. It weighs 21.7 kg, which is 23% lighter than stock. Power gains of 8.7 kW (11.8 hp) at 5,600 rpm and torque increases of 17.1 Nm at 4,100 rpm were recorded when tested on the Akrapovi dyno against a BMW M440i with a standard stock exhaust. Special parts are cast in the Akrapovi in-house foundry to create the intricate and complex items needed for this system. Meant for track use only and for non-OPF vehicles, remapping is recommended with this product.
