Titanium 3-into-1, approved for WSSP competition, with the four carburation ports that let a tuner read each cylinder separately. You buy it alone when you already run a Spark silencer, when a crash has claimed the pipework but not the muffler, or when you are building a race bike section by section.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTitanium collector, 3-into-1, to World Supersport specification.\u003c\/li\u003e\n\u003cli\u003eFour carburation ports — one at each cylinder connector, one downstream of the 3-into-1 junction.\u003c\/li\u003e\n\u003cli\u003eSame component fitted to the complete GYA8801T system.\u003c\/li\u003e\n\u003cli\u003eCNC-machined couplings so the silencer locates repeatably every time it comes off.\u003c\/li\u003e\n\u003cli\u003eDesigned around a Supersport chassis; not compatible with passenger footpegs.\u003c\/li\u003e\n\u003cli\u003eSupplied without a silencer — pair it with a Spark Force Evo, Konix Evo, Grid-O or Moto GP silencer group.\u003c\/li\u003e\n\u003cli\u003eMade by Spark in Mantova, Italy.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality \u0026amp; Materials\u003c\/h2\u003e\u003cp\u003eTitanium tube, hand-TIG-welded, with connectors machined from solid bar rather than pressed or spun. On a header that matters more than it does on a silencer: the manifold carries the highest gas temperature in the system and takes the mechanical load of everything hanging behind it. A pressed coupling that goes slightly oval under heat turns into a leak at the joint; a machined one does not.\u003c\/p\u003e\u003cp\u003eThe four sensor ports are a racing detail rather than a styling one. With one boss per cylinder plus one after the junction, a dyno operator can see whether cylinder three is running lean without inferring it from a mixed reading taken downstream of everything.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Sound\u003c\/h2\u003e\u003cp\u003ePipe lengths, diameters and taper rates come out of Spark's Supersport programme, where the same geometry runs a full season. This is a competition header: it is drawn for peak flow rather than mid-range manners, and it expects a matching map. Sound depends entirely on which silencer you put behind it — the header contributes almost nothing to attenuation on its own.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R9, 2025 and 2026, in Supersport configuration. Passenger footpegs cannot be fitted alongside it. If your R9 is otherwise standard, GYA8802 is the collector drawn for the original chassis instead — same material, different mounting.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNone whatsoever.
