This is a top-of-the-range full system beautifully crafted from high-grade ultra-lightweight titanium. It is the lightest Akrapovi? complete exhaust system, weighing just 4.4 kg – which is over 57% lighter than the stock system. The muffler and headers are constructed entirely from titanium. Its distinctive shape was developed especially for the Suzuki GSX-R1000 based on Akrapovi?’s vast racing experience. Increased power and torque through the whole rpm range, especially in the mid range and top end, add over 10 hp at 9,000 rpm and more than 9 Nm at 7,600 rpm, making this the best Akrapovi? exhaust upgrade for performance. The deep, true racing sound is perfectly tuned to match the increased performance. It offers easy-to-fit installation.For perfect performance, throttle response, and durability, special mapping developed by Akrapovi?
