Stillen is known for specializing in car and truck modding parts, including engine components, exhaust systems, superchargers and turbos, performance brake kits, coilover systems, exterior and interior accessories, and more. All of these parts and accessories are backed by the racing success of the company's founder, Steve Millen, who has been a professional racer for over 30 years. Beginning with 24 Hours of Daytona and ending with Nissan Prototypes at Le Mans, Steve has been victorious on racetracks the world over.

Steve Millen has captured several prestigious titles, including IMSA GT Driver's Championship, while being behind the wheel of his Nissan 300ZX Twin Turbo race car. His list of victories has earned him the title of being one of the most victorious drivers in IMSA GT history. And of course, this very legacy has brought Steve to test some of the finest and most powerful sports autos in the world, while developing his business in performance parts. For Stillen, this means engineering and manufacturing parts which are thoroughly tested and rigorously proven at the racetrack to work. Stillen constantly continues perfecting its existing parts.

There are plenty of automotive media, including Super Street, The Smoking Tire, DSport, AutoWeek, Automobile, Motor Trend, Road & Track, Car & Driver, and others, which have tested Stillen performance products and project autos and gave them excellent feedback. It is exactly the type of professional evaluation in real-world conditions that give Stillen a noteworthy edge over the competition with its products. Stillen superchargers will jam-pack your thoroughbred with plenty of fuel and air. Stillen intake systems will deliver plenty of fresh cool air in order for it to be mixed with racing gasoline and ignited. And Stillen exhaust will be as unrestrictive as possible, all in order to offer the maximum horsepower and torque gains!

I had this installed on my G37 and it completely transformed the sound! At idle it's quiet but once you get on the throttle, it roars! Not too loud to be annoying, just perfect.
