MB Twister mini bike header designed for GX200, Predator 212, and 196cc clone engines. Featuring a .880" inner diameter and curved “twister” design, this header improves low-end torque while providing better frame clearance for mini bike builds. See full product details below.
The MB Twister mini bike header is engineered for mini bike applications where space and routing are limited. The twisted pipe design allows the header to route around frame components more easily than a straight pipe, making installation cleaner and more flexible.
With a .880" inner diameter, this header maintains strong exhaust velocity, improving low-end torque and throttle response. This makes it ideal for trail riding, recreational use, and mini bike setups that prioritize quick acceleration over high-RPM top-end performance.
The outlet is designed to fit common clamp-on mufflers, making it easy to pair with performance mufflers such as RLV-style exhaust systems.
This header is designed to improve:
Compared to straight headers, the Twister design allows better fitment while maintaining similar torque-focused performance characteristics.
Important Fitment Notice: Designed for mini bike applications. Frame clearance should be verified prior to installation.
This header fits GX160, GX200, Predator 212 (Hemi and Non-Hemi), and most 196cc clone engines.
The curved design improves frame clearance and routing, making installation easier on mini bikes with tight layouts.
The .880" diameter helps improve low-end torque and throttle response, making it ideal for mini bike use.
No. This header is designed for mini bike applications. Kart racing setups typically use multi-stage headers.
Yes. A brace is recommended to prevent cracking due to engine vibration and movement.
Complete your mini bike or kart engine build with ARC Racing performance components including billet flywheels, billet connecting rods, carburetors, and exhaust components designed for GX200, Predator, and clone engines.
