This header features a 22mm internal diameter, which is smaller than the senior header, and is designed to restrict exhaust flow for junior class KA100 racing. The smaller diameter alters the powerband to produce less peak power, making it appropriate for younger and lighter drivers in junior categories.\u003c\/p\u003e\n\u003cp\u003eThe junior header is mandated by class regulations in junior KA100 divisions. Using the wrong header (senior vs junior) will result in a technical inspection failure. Always verify your class rules to confirm which header is required. The junior header mounts identically to the senior version — same exhaust studs, same silencer connection.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Junior exhaust header, 22mm internal diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e IAME KA100 — junior class\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 header pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRequired for junior KA100 classes.
