The Agency Power Titanium Exhaust System for the Nissan GT-R is the ultimate lightweight solution. The entire exhaust is made of rare ultra lightweight titanium. Not only will this exhaust give you more power but because it weighs so much less then the factory exhaust, you will get a better power to weight ratio. Shaving weight is the number one way to increase your cars handling, off the line acceleration, and decrease stopping length. The titanium system is has multiple benefits aside from lightness; it greatly improves the exhaust flow and helps to prevents heat soak. There is a reason titanium is so highly used in Motorsports, Technology, and Aero Space programs. Why should they have all the fun? The larger piping paired with the 1mm walls is the perfect combination for more power, a race car sound, and weight savings.
