Switch between a quiet cruising mode and a loud performance mode, with less drone when the valves are closed.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-light titanium\u003c\/li\u003e\n\u003cli\u003eHigh-flow catback design for better exhaust flow and sound\u003c\/li\u003e\n\u003cli\u003eValve control for comfort or full volume\u003c\/li\u003e\n\u003cli\u003eOEM integration available for factory-style operation\u003c\/li\u003e\n\u003cli\u003eMandrel-bent piping with precision TIG welds\u003c\/li\u003e\n\u003cli\u003eOptional free-flow downpipes (separate item) add volume\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe valved layout gives the V8 two useful characters: quieter cruising with the valves closed and a stronger exhaust note when they open. The high-flow cat-back design, mandrel-bent tubing and TIG-welded joints are intended to work as one exhaust system instead of a set of unrelated rear-section parts.\u003c\/p\u003e\u003cp\u003eThis is the titanium cat-back SKU MER.X290.GT63.VSES.TI. The manufacturer offers front free-flow pipes as a separate configuration, which changes the volume and the exhaust hardware ahead of the cat-back. They are not included here. The table identifies the X290 four-door platform, not the newer two-door AMG GT with a similar model name.\u003c\/p\u003e\u003cp\u003eThe titanium system is the exhaust assembly sold by this SKU; exhaust tips, clamps and installation hardware are described as included by the manufacturer. Front free-flow downpipes are optional in the wider product family but not part of this cat-back selection. That difference matters when comparing kits that appear similar in photographs but replace different portions of the exhaust.\u003c\/p\u003e\u003cp\u003eValvetronic describes a deep V8 tone, electronic valve operation and available OEM integration. The aim is a useful closed mode for cruising and a louder open mode under load, rather than a permanently open exhaust. The manufacturer specifies a reversible direct-fit installation and recommends professional work. No particular power increase or ECU calibration is bundled or guaranteed on this page.\u003c\/p\u003e\n\u003ch2\u003eWhat is included\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eTitanium valved catback exhaust system\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch2\u003ePart numbers and configuration\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eMER.X290.GT63.VSES.TI\u003c\/strong\u003e - Catback System Only.\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: titanium\u003c\/li\u003e\n\u003cli\u003eType: valved catback\u003c\/li\u003e\n\u003cli\u003eEngine: AMG 4.0L twin-turbo V8\u003c\/li\u003e\n\u003cli\u003eSKU: MER.X290.GT63.VSES.TI\u003c\/li\u003e\n\u003cli\u003eManufacturer application \/ configuration: Catback System Only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFitment notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDirect-fit catback.
