This is the senior (full-size) version of the header, designed for senior class KA100 racing. The header's internal diameter and length are tuned to complement the KA100 engine's powerband characteristics.\u003c\/p\u003e\n\u003cp\u003eThe exhaust header is a critical tuning component on a two-stroke engine — its dimensions directly affect exhaust pulse timing, scavenging efficiency, and overall power output. The header mounts to the cylinder via two exhaust studs and connects to the silencer via a flexible spring. Replace the header if it shows cracks, dents, heavy corrosion, or if the mounting flange is warped.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Senior (full-size) exhaust header\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e IAME KA100 — senior 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\u003eA damaged or dented header alters exhaust pulse timing and costs power.
