Modelix Racing have introduced new version of the Ultimate Racing EFRA 2141 and EFRA 2142 Super Strong Fast-Lock exhaust systems. Both high-quality aluminium pipes incorporate the Fast-Lock system and the location of the pressure tap has been modified for better performance. The EFRA 2141 pipe provides a precise and linear throttle response in the low to mid RPM range with a great top end speed. This pipe set will provide great power to your engine up to the high RPM range to produce a great and easy to drive power curve. All these characteristics will provide great torque for those very demanding tracks with sharp corners and hard to clear jumps.

The EFRA 2142 provides a precise and linear throttle response in high RPM range with a great top end speed. This pipe set will provide great power and speed at high RPM. It’s the perfect choice for big tracks with long straights where high speed is needed. Both exhaust systems include the pipe, the manifold with O-ring and gasket seals, 2 medium springs, 2 long spring and 1 manifold gaskets.
