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.","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":43403633033279,"sku":"ak_S-A6R4-HAPC","price":1941.84,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0667\/3213\/0367\/files\/ak_S-A6R4-HAPC_b.jpg?v=1781603462","url":"https:\/\/vaultmoto.com\/products\/akrapovic-racing-line-carbon-s-a6r4-hapc-ak-s-a6r4-hapc","provider":"Rydr Parts","version":"1.0","type":"link"}
