2009-2021 Nissan GT-R


The HKS Legamax exhaust system for the GT-R not only looks great and is made with the highest quality materials and machines but is also quiet and only 1db above the stock exhaust system. That is where the similarities end, this exhaust system will outflow and outperform the stock system in every way. It is designed with performance in mind and has been carefully created and tested to maximize this on the GT-R. The full 3" mandrel bent 304 stainless steel enhances the already unique sounding GT-R and really gives it an aggressive tone that stands out without droning. The system is a direct bolt on and requires zero modification for installation.

  • Improves both horsepower and torque
  • Improves throttle response with reduced turbo lag
  • Creates a very aggressive exhaust sound
  • 304 stainless steel construction
  • 3" inch piping diameter leading to the muffler
  • Quad burnt titanium exhaust tips
  • 4.75" inch round tip size
  • Includes new gaskets and hardware for the installation

Great sound, great price!

Wanted to get an exhaust setup that wasn’t too much louder than stock. This was the right setup without a doubt. IIR got me taken care of fast!
