Just got in the Fabspeed Sport Cat Converter X-Pipe system to solve CEL. Decided to also add the Fabspeed Carbon Fiber Comp Air Intake system. Cat system adds 25 HP and 32 FT-LBS torque. Air intake adds 24 HP and FT-LBS torque. Question: Do these gains stack together on top of each or is it a blend? What numbers should I expect to see? Thanks!
