Concealed behind these aggressive tail pipes is the hard work of the Akrapovič R&D team. Substantial work was required to achieve the 17 horsepower output and 56 Nm/42 lbs-ft of torque increase over stock. These gains were not only realized at redline but throughout the entire rpm range of the engine. Additionally, we were able to reduce the weight by over 17 kg/38 lbs. when compared with the stock system. The entire titanium Evolution system weighs in at only 14 kg/32 lbs. The power-to-weight ratio improves on both fronts: power increase and weight reduction.
The GT-R system was designed to have an aggressive, yet sporty sound. Droning, which can ruin the entire driving experience, was carefully tuned out. You can also choose either titanium or carbon fiber tail pipes.
