The REDS WR5 Efficiency Pack .21 Nitro Engine Combo includes the awesome WR5 engine, combined with the 2104 X-ONE Smooth pipe and 6, 7 and 7.5mm venturis.

The WR5 .21 engine is a 5 port off road engine based on the famous R5T Team Edition engine that has been a staple in the REDS lineup for 6 years. The WR5 is available in two different models - the standard WR5 Black Diamond that offers the REDS 5 port high torque power band, and the WR5 Black Diamond HE High Efficiency that offers low fuel consumption system and smooth power band for high driveability.

The REDS Racing X-ONE 2104 One-Piece Off-Road Tuned Pipe is an innovative all-in-one pipe-manifold system. The pipe has been welded to the manifold to improve performance and fuel consumption. With X-ONE configuration there is no need for springs or gaskets, and the one piece design creates increased reliability and improved tuning stability.
