The Evolution gives more power, higher torque, decreases the weight, and delivers an unmistakable Akrapovic sound—which has a deep sound at lower revs and a \"popping’ sound as things speed up when the throttle is lifted.This titanium exhaust system has cast collectors and three mufflers, with the central one featuring an x-piece inside, which increase power and improve its sound. The valves of the system are designed to open and close in line with the RS’ standard electronics, and the whole system has carbon-fiber tailpipes to show off the exquisite finish of the Akrapovic exhaust.Its easy-to-fit instructions are included, and with this cat-back performance exhaust system—which means that the stock catalytic converters remain in place—there’s no need to remap the ECU (it’s simply a plug-and play system).\nFEATURES:\n \n\nInstall Instructions","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/S-AU-TI-4H-2_49d7d121-72b9-4ee5-aa38-6624728b19f8_grande_jpg.webp?v=1766326270"],"price":10154.59,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:22.730Z"},"share_url":"https://firestarter.network/l/lst_RSs2fACf","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
