{"product_id":"racing-line-complete-exhaust-carbon-fiber","title":"Racing Line Complete Exhaust - Carbon Fiber","description":"Designed to optimize power and torque from the 660 cc parallel-twin powerplant, this system meets EC\/ECE type approval, making it fully Euro 5 compliant. 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 fiber, 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 Akrapovic 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 Akrapovic Racing Line (Carbon) for the Aprilia RS 660 the ideal exhaust for this middleweight sports bike.","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":52558010810677,"sku":"FGWP_S-A6R4-HAPC","price":2177.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/4697\/0933\/files\/18102881_0.png?v=1775901872","url":"https:\/\/ad-discountpowersports.com\/products\/racing-line-complete-exhaust-carbon-fiber","provider":"A\u0026D Discount Performance","version":"1.0","type":"link"}
