We have released our True 3" Inner Diameter Inlet pipe because this is quite a huge a restriction for the 2009-11 GTR and still a small restriction for the 2012-13 GTR especially if you plan on upgrading the cartridge in your stock turbochargers. The 2 Bolt side has a larger inner for future turbo upgrades but still retains the stock 2 bolt dimensions. This still retains the crank case hook up. It also still allows you to recirculate your blow off valves if you so choose.
