The HKS Legamax exhaust system for the GTR 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 GTR. The full 3" mandrel bent 304 stainless steel enhances the already unique sounding GTR and really gives it a tone that stands out. The system is a direct bolt on and requires zero modification for installation.
