The HIPEX 21 R4 exhaust manifold is a high-performance manifold designed exclusively for OS-based engines.
It replaces the HIPEX M321 manifold and is specifically designed for ENS racing.
Designed for durability and optimal exhaust flow, it significantly improves engine efficiency while delivering excellent power and smooth low-rpm delivery.
The 30° tilt lowers the center of gravity, ensuring greater stability and driveability for your RC car.
