Ultimate Racing EFRA 2141 & 2142 exhaust systems

Coming from Modelix Racing are the updated Ultimate Racing EFRA 2141 and EFRA 2142 Off-road Super Strong exhaust systems. On both sets the location of the pressure tap has been modified for better performance and both come with the Fast-Lock pipe and manifold connecting system for easy and reliable connection of the exhaust pipe and manifold. Performance-wise the EFRA 2141 pipe provides a precise and linear throttle response in the low to mid RPM range with great top end speed while offering an easy to control power curve for very demanding tracks with sharp corners and hard to clear jumps. The EFRA 2142 set provides a precise and linear throttle response in the higher RPM range with a great top end speed, making it the perfect choice for big tracks with long straights where high top speed is needed.
