Hasi Tuned .21 manifolds
Hasi Tuned have released 4 new manifolds for .21 engines, the first of which is a conical manifold that guarantees easy tuning and low fuel consumption. This is great for middle fast track were there is normally high fuel consumption. The 2nd is a conical 90° version and offers more torque in the low and middle rpm and is a perfect choice for fast tracks. The 3rd version is a conical 90+90 and has extreme torque making it a good choice for super fast track and there is a 4th version which is slightly longer for a little bit simpler tuning and with less consumption than the std version.
