The HIPEX 21 B7 parabolic manifold is the conical version of the L50 manifold.
Designed for high-performance OS-based engines, it was developed to optimize gas dynamics.
The conical parabolic geometry of the manifold allows for:
• Improved flow velocity at low revs
• Increased usable return pressure
• More progressive and linear power delivery
• Optimized response out of corners
It pairs perfectly with the 2135 EVO2 and 2135 EVO3 exhaust pipes.
Suitable for any type of track. Excellent power delivery at low revs. Reduced fuel consumption by over 30 seconds.
 
Results on the track
✔ Increased low-end torque
✔ Improved traction in technical sections
✔ More controllable power delivery on low-grip surfaces
✔ Over 30 seconds of fuel consumption reduction
