The number appears in the parts diagrams of 10 different Akrapovic systems — it is hardware the systems share, not a part built for one motorcycle.\u003c\/p\u003e\n\u003cp\u003eThe header sits closest to the engine and runs hottest of any part of the exhaust — it is where discolouration starts and where a crack shows up first. Header tubes are numbered per cylinder on multi-cylinder systems; the lengths differ and they are not interchangeable between positions.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Akrapovic part from the official spare-parts programme\u003c\/li\u003e\n\u003cli\u003ePart number H-Y9R4\u003c\/li\u003e\n\u003cli\u003eDocumented in the parts diagrams of 10 Akrapovic systems\u003c\/li\u003e\n\u003cli\u003eCategory: Header Tube\u003c\/li\u003e\n\u003cli\u003eA single header can be replaced without the rest of the system, which is the point of Akrapovic selling them separately\u003c\/li\u003e\n\u003cli\u003eEAN 3831113593182\u003c\/li\u003e\n\u003cli\u003eSupplied without a manufacturer photograph\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhich exhaust system this part belongs to\u003c\/h2\u003e\n\u003cp\u003eThe list below comes from Akrapovic's own parts diagrams — the number is printed in each of these:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R11-HAPT) — Yamaha MT-09\/FZ-09, 2022\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R13-HAPT) — Yamaha Tracer 9 \/ GT \/ GT+, 2024\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R13-HAPT\/1) — Yamaha TRACER 9, 2021–2024\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R15-HAPT) — Yamaha MT-09\/FZ-09, 2023\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R15-HAPT\/1) — Yamaha FZ-09 and MT-09, 2021–2023\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R15-HAPT\/2) — Yamaha FZ-09 and MT-09, 2024–2026\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R16-HDT) — Yamaha XSR 900 \/ GP, 2023\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R16-HDT\/1) — Yamaha XSR 900 \/ GP, 2023\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R16-HDT\/2) — Yamaha XSR900, 2022–2026\u003c\/li\u003e\n\u003cli\u003eRacing Line (Titanium) (S-Y9R17-HAPT) — Yamaha R9, 2026\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat Akrapovic publishes for this part\u003c\/h2\u003e\n\u003cp\u003eThe part number, the EAN, the category and the price — nothing more. For spare parts of this kind Akrapovic publishes no photograph, no description, no material specification and no dimension. We deliberately do not assign this part to a single motorcycle. It is documented in the diagrams of several different systems, so a filter entry for one bike would be misleading rather than helpful.\u003c\/p\u003e","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":53632703267082,"sku":"H-Y9R4","price":364.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/H-Y9R4.png?v=1788656905","url":"https:\/\/inter-pace.com\/en-pe\/products\/akrapovic-header-tube-h-y9r4","provider":"Inter-Pace","version":"1.0","type":"link"}
