That is the design decision that lets a Hayabusa keep full Euro 5 EC and ECE type approval while losing 3.9 kg of exhaust — and it is why this system measures exactly the same 91.9 dB as the standard one while sounding nothing like it. The Akrapovic Slip-On Line (Titanium) S-S13SO4-HRAATBL\/1 is the black-coated version.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eA catalytic converter inside each of the two mufflers, which is what preserves Euro 5 EC and ECE type approval on a machine with this much displacement\u003c\/li\u003e\n\u003cli\u003e8.39 kg against the standard 12.27 kg: 3.9 kg and 31.6 per cent less\u003c\/li\u003e\n\u003cli\u003eBlack-coated lightweight titanium outer sleeves, high-grade stainless steel link pipes, carbon fibre end caps and carbon fibre heat shields\u003c\/li\u003e\n\u003cli\u003eAero-efficient muffler shape drawn to match the Hayabusa's own bodywork rather than sit on top of it\u003c\/li\u003e\n\u003cli\u003eLaser-engraved Akrapovic logo instead of a decal\u003c\/li\u003e\n\u003cli\u003e91.9 dB at 4,850 rpm — the same measured figure as standard, with a completely different character\u003c\/li\u003e\n\u003cli\u003e1.6 PS (1.2 kW) more at 8,700 rpm and 1.9 Nm more at 8,400 rpm, plug-and-play with no remapping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSame Decibels, Different Bike\u003c\/h2\u003e\n\u003cp\u003eThe noise measurement is worth dwelling on because it is unusual: standard 91.9 dB, Akrapovic 91.9 dB, a difference of exactly zero. A type-approved exhaust has to stay inside a legal window, and Akrapovic hit the same number rather than creeping up to the limit. What changes is the tone — a 1,340 cc four through short, wide titanium cans is a fundamentally different sound from the same engine through the standard system, without being louder on a meter.\u003c\/p\u003e\n\u003ch2\u003eConstruction\u003c\/h2\u003e\n\u003cp\u003eBlack coating over titanium is a durability choice as much as a visual one. On a machine that covers long distances at speed, an uncoated titanium sleeve discolours unevenly around the clamp; the coating keeps the finish consistent. The end caps and both heat shields are carbon fibre, and the link pipes are stainless steel where the catalytic converters generate their heat.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eS-S13SO4-HRAATBL\/1 fits the Suzuki Hayabusa GSX-1300R from model year 2021 through 2026. Two notes from Akrapovic: the system fits Euro 5+ motorcycles equipped with two lambda sensors, and it was developed and tested on EU-specification machines — fitment and measured performance on bikes built for other markets can differ. Installation takes about 45 minutes and a noise insert is supplied.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eEC type approval and ECE type approval to Euro 5, with the certificates supplied and downloadable from this page. Because a catalytic converter stays in each muffler, nothing is removed from the emissions path and the machine remains legal for road use in the European Union.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: S-S13SO4-HRAATBL\/1\u003c\/li\u003e\n\u003cli\u003eEAN: 3831126442163\u003c\/li\u003e\n\u003cli\u003eFitment: Suzuki Hayabusa GSX-1300R (2021–2026)\u003c\/li\u003e\n\u003cli\u003eSystem type: slip-on, two mufflers\u003c\/li\u003e\n\u003cli\u003eOuter sleeves: titanium, black coated\u003c\/li\u003e\n\u003cli\u003eLink pipes: stainless steel\u003c\/li\u003e\n\u003cli\u003eEnd caps and heat shields: carbon fibre\u003c\/li\u003e\n\u003cli\u003eCatalytic converters: one in each muffler\u003c\/li\u003e\n\u003cli\u003eSystem weight: 8.39 kg (stock 12.27 kg, saving 3.9 kg \/ 31.6 %)\u003c\/li\u003e\n\u003cli\u003ePower: 186.3 PS at 9,500 rpm (stock 185.1 PS at 9,600 rpm, gain 1.6 PS \/ 1.2 kW at 8,700 rpm)\u003c\/li\u003e\n\u003cli\u003eTorque: 154.4 Nm (stock 153.0 Nm at 7,100 rpm, gain 1.9 Nm at 8,400 rpm)\u003c\/li\u003e\n\u003cli\u003eSound level: 91.9 dB at 4,850 rpm (stock 91.9 dB)\u003c\/li\u003e\n\u003cli\u003eNoise insert: included\u003c\/li\u003e\n\u003cli\u003eInstallation time: approx. 45 minutes\u003c\/li\u003e\n\u003cli\u003eRoad approval: EC and ECE type approval, Euro 5\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Slovenia\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":53626769539338,"sku":"S-S13SO4-HRAATBL\/1","price":2211.62,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01_e9033c0f-d629-462b-8fe6-fac2a5cfd365.png?v=1788512309","url":"https:\/\/inter-pace.com\/en-bg\/products\/akrapovic-slip-on-line-titanium-suzuki-hayabusa-s-s13so4-hraatbl-1","provider":"Inter-Pace","version":"1.0","type":"link"}
