Ultimate Racing EFRA 2142 Fast-Lock exhaust system

Modelix from Spain have introduced the new Ultimate Racing EFRA 2142 Fast-Lock Super Strong exhaust system for 1/8th off-road kits. The Fast-Lock system allows to connect the pipe and manifold without the usual springs for a stronger and more reliable alignment and improved engine performance. The pipe and manifold are equipped with O-ring and gasket seals and the design of the exhaust provides a precise and linear throttle response in the low to mid RPM range while ensuring exceptional top speed. The exhaust was designed for the use with Ultimate’s M4R, M5 and M8 engines and the set includes the pipe, manifold, three short springs, 2 medium length springs as well as a single long spring as well as the manifold gaskets.
