The Infiniti G series comes sporting a very nice sounding and performing exhaust system.We also know that you want to kick it up a notch or two by swapping out the stock restrictive exhaust for the HKS Hi-Power. Also you may be thinking why is this exhaust much more expensive than other brands on the market. Which there are only a few of. Reason being is that either brands simply use a design that is not specific for the G37. HKS has done the correct R&D to bring to you the proven specs for you to increase performance while maintaining the G series safety. Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated G37's. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path. For turbocharged  G35 & G37 series, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Certain applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler.
