With the catalytic converter located in the front part of the pre-muffler, to ensure the system fully complies with the regulation, the system has a plug-and-play installation with no remapping needed. Constructed from high-quality carbon fibre, lightweight titanium, and high-grade stainless steel, the system has been created using race-proven materials. Designed to emphasize the racing look of the machine, the system is 0.4 kg lighter than standard stock. Testing on the Akrapovič in-house dyno, in back-to-back runs of bikes equipped with a Racing Line (Carbon) exhaust and standard stock exhaust system, recorded an increase of 2.4 hp at 11,200 rpm and a gain of 3.6 Nm of torque at 4,550 rpm, which gives the rider a pronounced throttle response. Its deep, full, and sporty sound, with its throbbing parallel-twin pulsations, offers the feeling of riding a bigger capacity bike, making the Akrapovič Racing Line (Carbon) for the Aprilia RS 660 the ideal exhaust for this middleweight sports bike.\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Aprilia RS 660 2021-2024; Aprilia Tuono 660 2021-2024\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePart number:\u003c\/strong\u003e S-A6R4-HAPC\u003cbr\u003e\u003cstrong\u003eEAN:\u003c\/strong\u003e 3831113596329\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHomologation:\u003c\/strong\u003e EC Type Approval, ECE Type Approval\u003c\/p\u003e","brand":"AKRAPOVIC","offers":[{"title":"Default Title","offer_id":54006127558932,"sku":"S-A6R4-HAPC","price":2562.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1259\/9599\/files\/01db8fb7-cb4c-423d-bd97-2a43e3d25d49_8b3377d6-4733-422c-be2a-0e5e0ab75950.png?v=1789225330","url":"https:\/\/www.dennispowersport.com\/zh\/products\/s-a6r4-hapc-s-a6r4-hapc","provider":"DennisPowerSport","version":"1.0","type":"link"}
