The Nissan GT-R is one of the fastest cars to race on Germany?s famous N?rburgring Nordschleife (North Loop). To enhance this already impressive performance, we offer our Akrapovic Slip-On exhaust system made completely of our proprietary titanium. This beautifully crafted sport exhaust achieves weight reduction and delivers power improvement, most noticeably at the top of the rpm range. The sound is also improved, with a deeper, sportier sound delivered without droning, and this perfectly complements the car. The attention to detail can be seen in every component. Even the exhaust tailpipes were designed to resemble the trademark GT-R tail lights. Complete the look with a set of four exquisite tailpipes in carbon fibre.When replacing the stock exhaust that includes valves, then the ECU remapping is mandatory!
