Your Stock Nissan GTR is quick car but adding a HKS GT600's Standard Racing Kit with the Legamax Premium Exhaust Package will make your GTR very fast. is an industry standard for quality and performance. HKS uses a pull type valve to ensure that this will never leak with any amount of boost. Unlike typical push type blow off valves, the HKS SQV will not leak under any level of boost because the boost pressure keeps the valve closed against its seat. This ensures a quick valve response and complete closure during idle. Many competitors use a push type blow off valve design with a large valve to accommodate high boost / high horsepower applications. The HKS Legamax Premium Exhaust package one of the more creative designs for the exhaust we've seen so far is this new release from HKS is a full 304 grade stainless exhaust package. The main pipe section is 3.35 inch in diameter and opens to four 4.7 inch tips at the rear. HKS Legamax Premium Exhaust package produces this stainless steel exhaust system with four titanium tips. The unique pipe configuration and affordable price using stainless steel are the main draws to this system.

Sound is kept nearly the same as OEM. The OEM dB rating is 88dB whereas this HKS Exhaust System is 89dB. The HKS exhaust  package has a large radius piping layout optimizes exhaust gas pressure and temperature allowing peak performance and an aggressive exhaust tone.These large valves react slowly and require high pressure to open, and are not able to activate and prevent compressor surge at light load conditions. The GTR uses two of these valves to relieve boost pressure from the twin turbo. This setup is highly effective and recalculates air quickly to prevent compressor surge. HKS Package has designed these to work on stock up to highly modified GTR. The standard Nissan GT-R R35 package kit is rated at 480 HP, but this kit is brings that number just over 600 HP at the flywheel by way of a new exhaust, intake pipe kit, boost controller and waste gate actuators. The GT600 Racing Package is intended for off-road / motor sports use only. The GT600's package is not covered under HKS warranty and is sold as-is.
