Carbon Smith 2020-2024 APRILIA RS660 DIMPLED VELOCITY STACKS FOR RACE EXHAUST

Our 2020+ Aprilia RS660 Velocity Stacks are an amazing upgrade to boost performance on your new Aprilia RS660!  After several hundred dyno runs, 15 different velocity stack configurations, and 15 gallons of fuel, CarbonSmith has finally finished developing the perfect velocity stack configuration for your RACE TRIM Aprilia RS660!  Changing the stock exhaust and OEM air filter allows for much different stoichiometric air/fuel mixture allowing us to change the targeted resonant frequency resulting in MORE POWER!!  We found +2 hp gains at multiple spots in the RPM curve with a simple drop in test!  More gains are possible with full custom dyno tuning!

THIS KIT INCLUDES A COMBINATION LEFT AND RIGHT VELOCITY STACK DESIGNED FOR OPTIMUM AIR/FUEL MIXTURE ACROSS THE ENTIRE RPM RANGE.  

DIMPLE DESIGN CREATES ADDITIONAL TQ AND HP AT HIGH SPEED.

MANUFACTURED WITH NYLON EMBEDDED CARBON FIBER REINFORCED WITH CONTINUOUS CARBON FIBER.  THIS MAKES THEM EXTREMELY STRONG, LIGHTWEIGHT, YET FLEXIBLE AND VERY RESISTANT TO HEAT AND CHEMICALS.  THESE SHOULD ONLY BE INSTALLED BY A PROFESSIONAL.
