That is not a side effect to discover later — it is stated on the slip-on's own page and it is repeated here, because the two parts are sold to be used together and the legal consequence belongs with both.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e5.7 PS more at 9,500 rpm, peak output rising from 73.4 to 79.1 PS\u003c\/li\u003e\n\u003cli\u003e4.9 Nm more at 4,800 rpm — where a loaded adventure bike climbs\u003c\/li\u003e\n\u003cli\u003e2.2 kg against the standard 5.09 kg: 2.9 kg and 56.8 per cent less\u003c\/li\u003e\n\u003cli\u003eLarger tube diameter than the standard header\u003c\/li\u003e\n\u003cli\u003eNo catalytic converter — unlike the standard version\u003c\/li\u003e\n\u003cli\u003eDeveloped for closed-course competition circuits only\u003c\/li\u003e\n\u003cli\u003eFigures measured in combination with the Slip-On Line (Titanium)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eThe Aprilia That Is Faster Than the Licence Allows\u003c\/h2\u003e\n\u003cp\u003eThe Tuareg 660 leaves the factory making 73.4 PS. With this header and the Akrapovic slip-on it makes 79.1 — comfortably above what a type-approved version of this motorcycle is allowed to produce in Europe.\u003c\/p\u003e\n\u003cp\u003eThat is the honest description of what this part is: a competition component that takes a road-legal adventure bike outside its homologation. On a closed course that is exactly the point.\u003c\/p\u003e\n\u003ch2\u003eA Bigger Pipe, No Converter\u003c\/h2\u003e\n\u003cp\u003eTwo changes drive the figures. The tube diameter is larger than standard, which lowers back pressure across the range, and the catalytic converter is gone entirely rather than relocated.\u003c\/p\u003e\n\u003cp\u003eThe 4.9 Nm at 4,800 rpm is the more interesting half. A bigger bore usually costs low-rev response, and this one does not — which suggests the standard header was restrictive enough that opening it helps everywhere.\u003c\/p\u003e\n\u003ch2\u003eMeasured With the Slip-On\u003c\/h2\u003e\n\u003cp\u003eAkrapovic measured these figures with the header and the Slip-On Line (Titanium) S-A6SO1-HGJT fitted together. That is the intended combination, and it is the one the numbers describe. The header on its own with a standard silencer has not been measured.\u003c\/p\u003e\n\u003ch2\u003eWhy the Fitment Stops at 2024\u003c\/h2\u003e\n\u003cp\u003eAprilia revised the Tuareg 660 for 2025 to meet Euro 5+, changing the exhaust route in the process. This header covers 2022 to 2024 and does not carry over. If your Tuareg is newer, ask us before ordering rather than after.\u003c\/p\u003e\n\u003cp\u003eThe Slip-On Line S-A6SO1-HGJT does cover 2022 to 2026 — so on a 2025 or 2026 machine the slip-on fits and this header does not. That mismatch is worth knowing before you order both together.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eE-A6R1 covers the Aprilia Tuareg 660 from model year 2022 through 2024.

Developed for use on closed-course competition circuits only. Fitting it also invalidates the EC\/ECE type approval of the Slip-On Line S-A6SO1-HGJT — the two parts together are a track configuration.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: E-A6R1\u003c\/li\u003e\n\u003cli\u003eEAN: 3831126409159\u003c\/li\u003e\n\u003cli\u003eFitment: Aprilia Tuareg 660 (2022–2024)\u003c\/li\u003e\n\u003cli\u003ePart type: optional header, no catalytic converter\u003c\/li\u003e\n\u003cli\u003eMaterial: high-grade stainless steel, larger bore than standard\u003c\/li\u003e\n\u003cli\u003eWeight: 2.2 kg (stock 5.09 kg, saving 2.9 kg \/ 56.8 %)\u003c\/li\u003e\n\u003cli\u003ePower: 79.1 PS (stock 73.4 PS, gain 5.7 PS at 9,500 rpm)\u003c\/li\u003e\n\u003cli\u003eTorque: 63.8 Nm (stock 61.6 Nm, gain 4.9 Nm at 4,800 rpm)\u003c\/li\u003e\n\u003cli\u003eMeasured with: Slip-On Line (Titanium) S-A6SO1-HGJT\u003c\/li\u003e\n\u003cli\u003eECU remapping: not required\u003c\/li\u003e\n\u003cli\u003eInstallation time: approx. 60 minutes\u003c\/li\u003e\n\u003cli\u003eRoad approval: none — closed-course competition only\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Slovenia\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":53627891941642,"sku":"E-A6R1","price":13151.8,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01_f935704a-3da7-4325-9dca-57a5ffcf100a.png?v=1788530919","url":"https:\/\/inter-pace.com\/en-cz\/products\/akrapovic-optional-header-stainless-aprilia-tuareg-660-e-a6r1","provider":"Inter-Pace","version":"1.0","type":"link"}
