This KA100 restricted exhaust manifold features a 27mm hole size, making it a larger header for the Junior class. It's important to note that most karting series prefer the 22mm Junior Header, so this 27mm option is less commonly used.

To use this exhaust manifold, first make sure your kart is compatible with a 27mm manifold. Install it carefully according to the kart's instructions. When using, keep in mind that it's not used by most karting series. As for maintenance, regularly check for any signs of damage or wear. Clean it occasionally to keep it in good condition. If you notice any issues, replace it promptly to ensure your kart runs smoothly.
