We designed our X-Pipe in such a way that it creates more useable horsepower, torque, and throttle response much sooner. The system produces an astonishing 60 lb/ft of torque over stock to the wheels at 3100 rpm and an additional 36 wheel horsepower at 3100rpm. Peak horsepower is an additional 16 to the wheels and peak torque comes in at additional 18 lb/ft over stock to the wheels. This system also provides dynamic sound quality via a custom resonator and muffler design with dual 90mm tips. ASR Stage I NOS Kit http://www.asrengineeringinc.com Stage I provides an additional 75hp to the wheels via an ASR designed custom nitrous system. Reliability and safety were of utmost concern when developing our system. This is why our kit also includes a re-flashed DME  custom nitrous file with special ASR air intake designed specifically for nitrous. We've also incorporated a digital window switch for safety. This commands the nitrous to turn on and turn off at a specific rpm so your nitrous will never stay engaged while on the rev limiter.
