This is the homologated EFRA 2141 Off-Road Super Strong Pipe Set with Fast-Lock System Manifold from Ultimate Racing. This hi-quality aluminium exhaust is an evolution of the previous 2141 version which incorporates the Fast-Lock system and the location of the pressure tap has been modified for better performance providing:
- Improvements to the power curve.
- Higher top speed.
- Better fuel mileage
This exhaust system 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.
This pipe set incorporates 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 are 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 lubricating the O-ring/gasket with a drop of after run oil when assembled for the first time.
This exhaust system includes the pipe, the manifold with O-ring and gasket seals, 2 medium springs, 2 long spring and 1 manifold gaskets.
