We have released our True 3" Inner Diameter Inlet pipe because this is quite a huge a restriction for the 2009-present 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. Now available with or without blow off valve recirculation tubes for those who prefer to use vent to atmosphere blow off valves
