EFRA 2113 X-ONE 

REDS off-road 2113 X-ONE™ Torque Pipe combines REDS 2113 Pipe and M Manifold to create this one-piece "High Power’’ exhaust. 2113 exhaust guarantees smoother power output at low RPM and higher mid range power and top speed.

Reds Racing was the first company to bring this innovative and unique X-ONEâ„¢ system to the market and thanks to the experience of our engineers and our team, we are taking it to levels never seen before.
Reds X-ONEâ„¢ system is an innovative and unique all-in-one pipe-manifold system. The pipe has been welded to the manifold to improve performance and fuel consumption. With this X-ONE configuration there is no need for springs or gaskets, and the one piece design creates increased reliability and improved tuning stability.
 
  • Main Features: Designed to maximize top-end speed and peak power while maintaining good torque. It has a smoother low-end response compared to the 2143.
  • Usage Target: Excellent for fast tracks with long straights and wide corners.
  • Advantages:
    • Better high RPM performance and increased top speed.
    • More suitable for racing conditions where acceleration is not the primary factor.


Two versions of the same 2113 X-ONEâ„¢ pipe-manifold system are now available:

KX210011: X-ONE PIPE 2113 TORQUE M  - STANDARD POLISH

KX210013: X-ONE PIPE 2113 TORQUE M - ULTRA COATING. The XONEâ„¢ 2113 ULTRA is built to withstand the rigors of racing. Its special Rainbow Hardening Treatment creates an ultra-hard surface, offering superior resistance to scratches and wear.

REDS X-ONE Torque 2143 One-Piece Off-Road Tuned Pipe combines  REDS 2143 Pipe and the REDS M Manifold to create this one-piece "Torque" exhaust.
 
The X-ONE system 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.
​​
  • Main Features: Designed to provide better low-end response and excellent torque delivery.
  • Usage Target: Ideal for technical tracks with frequent restarts, where extra low-end power is needed.
  • Recommended Pairing: Works well with the REDS M manifold to balance torque and top-end power.
  • Advantages:
    • Greater acceleration and traction out of corners.
    • More control in slow sections of the track.

​

​

Compared to the standard 2143 version, the new High Torque Plus has been developed to deliver:
​
  • Increased low-end torque, for quicker throttle response out of corners
  • Excellent top speed, ideal for high-speed tracks and long straights
  • Improved fuel efficiency: thanks to the new internal design, fuel consumption is significantly reduced, with an average gain of 40 seconds up to 1 minute compared to the standard 2143
  • More stable idle, allowing for more precise and consistent engine tuning
 
The 2143 XONE High Torque Plus is compatible with all REDS Racing off-road engines, but it delivers the best performance when paired with the 721 Pro-X engine, offering outstanding power and control in all conditions.
This exhaust is suitable for any type of track, but it excels in high-grip conditions, and when increased torque is needed out of corners or to clear double and triple jumps with ease.
