{"product_id":"valvetronic-cat-back-exhaust-system-3","title":"Valvetronic Cat-Back Exhaust System","description":"The FI EXHAUST Valvetronic Cat-Back Exhaust System is engineered for the Mercedes-Benz W167 AMG GLE63\/GLE63S featuring the 4.0TT M177 engine, compatible with 2020 and newer models. This system is designed exclusively for non-OPF vehicles and comprises a front pipe, mid X-pipe, and a valvetronic muffler, retaining OEM valve settings.\n\nConstructed from premium T304 stainless steel with mandrel-bent tubing and TIG welding, this direct bolt-on system is built to deliver an exhilarating soundtrack. The valvetronic technology allows for precise control over airflow, sound volume, and performance. During low-profile cruising, the closed valves ensure a comfortable ride, while fully open valves unleash an intense and sporty sound. Switching between modes is seamless, controllable via factory buttons or an optional Fi Pro remote upgrade.\n\nEach Fi EXHAUST system is hand-built to order at Fi's Taiwan facility, with a lead time of approximately 4-8 weeks. Due to the bespoke nature of these systems, all sales are final with no refunds, returns, or cancellations once production begins. Customers are advised to confirm fitment with the seller via VIN, trim package, and any existing modifications *before* placing an order. Catback-only systems, like this one, do not require a tune as the valves operate using the factory exhaust control signal. However, catless downpipes or headers (sold separately) will require a tune or O2 simulator and may trigger a Check Engine Light (CEL).\n\nProduct images may sometimes show optional downpipes or headers, which are not included and must be purchased separately.","brand":"AMG Performance","offers":[{"title":"Default Title","offer_id":52686925922616,"sku":"MB-167A-CBOE","price":5300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661658618.jpg?v=1784878526","url":"https:\/\/store.motormia.co\/products\/valvetronic-cat-back-exhaust-system-3","provider":"MOTORMIA","version":"1.0","type":"link"}
