Description
Ultimate Racing presents the FAST-LOCK system for connecting the exhaust pipe to the manifold without the pipe/manifold springs. This FAST-LOCK connecting system is stronger and safer than the traditional springs system, it ensures perfect pipe-manifold alignment and improves engine performance.
Assembly and operation is very easy. The manifold is fixed to the pipe by turning a quarter turn. The manifold comes with an inner silicone O-ring and an outer silicone gasket that ensures a perfect sealing. We suggest to lubricate the O-ring/gasket with a drop of after run oil when assembled for the first time.
Ultimate Racing has incorporated this FAST-LOCK system to the already existing well known Super Strong EFRA 2141 exhaust system. This EFRA 2141 hi-quality aluminum exhaust has been designed to improve the overall performance of your engine. It produces 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.This EFRA 2141 exhaust system is a great choice for your 1:8 off road engine, and it’s specially recommended for the M3R, M3X, M4R and M5 Ultimate engines
This exhaust system includes the pipe, the manifold with O-ring and gasket seals, 2 medium springs, 2 long spring and 1 manifold gaskets.
