Nitrous Express 50-300 horsepower Pro EFI Direct Port System with 12 pounds Composite Bottle for 8-Cylinder LT1 and LS1 Engines is the answer when space is tight but performance is still a requirement. At just half the size of its big brother, the Shark, the patented Piranha nozzle still packs a powerful bite. Designed specifically for the GM LT1/LT4 intakes, this system fits perfectly in the F-Body or Corvette. The LT1 Pro is adjustable from 50-300 horsepower. Nitrous system comes complete with nitrous bottle, stainless bottle brackets, next generation rail, stainless hard lines, nozzles, jetting, and all necessary electrical components. This system requires the drilling and tapping of intake and NX rail.
