ULTIMATE EFRA 2141 OFF ROAD SUPERSONIC PIPE SET W/ MANIFOLD

This is the Ultimate Racing Super Strong EFRA 2141 exhaust system.  In this SUPERSONIC update, the gas flow has been improved to achieve a higher top end speed compared to its predecessor. 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.

All these characteristics will provide great torque for those very demanding tracks with sharp corners and hard to clear jumps.
