{"product_id":"active-valve-cat-back-exhaust-system","title":"Active Valve Cat-Back Exhaust System","description":"The Milltek SSXFD420 Cat-Back Exhaust System is engineered for performance enthusiasts seeking to elevate their Ford Mustang's auditory and visual appeal. This system integrates active valve technology, allowing seamless transitions between quiet cruising and aggressive performance modes, fully compatible with factory drive modes.\n\nAt its core, the H-pipe crossover section is designed to equalize exhaust gas pressure between cylinder banks, producing a deep, traditional V8 rumble that emphasizes lower frequencies. This makes it an ideal acoustic upgrade for owners of the 5.0L Coyote engine who desire a muscular and commanding exhaust note without excessive rasp.\n\nConstructed from premium 304L \"Aircraft\" Grade stainless steel, the SSXFD420 ensures exceptional longevity and resistance to corrosion, even in demanding environments. The system features high-flow, mandrel-bent tubing with a 3-inch (70mm) diameter to maximize exhaust velocity and reduce backpressure, potentially leading to performance gains. The visually striking quad 115mm (4.5-inch) GT-115 polished tips add a custom aesthetic.\n\nInstallation is designed to be a direct replacement for the original system, with an estimated fitting time of 1.5 to 2.5 hours. The system comes with a Limited Lifetime Warranty, underscoring Milltek's commitment to quality. This cat-back system is specifically designed to fit the 2021-2026 Ford Mustang Dark Horse and Mach 1 models.","brand":"Milltek","offers":[{"title":"Default Title","offer_id":52689136746808,"sku":"SSXFD420","price":2651.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687384731.jpg?v=1784902392","url":"https:\/\/store.motormia.co\/products\/active-valve-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
