Description

Milltek valved resonated cat-back exhaust system for Ford Mustang 2.3L (S550/S650 fastback). T304L stainless steel construction with hand-finished burnt/blue titanium trim tips. Direct OEM+ fitment using factory hangers-no modification required. Requires OE GT 5.0 rear diffuser for installation. Engineered tone tuning targets resonance points across the rev range, delivering controlled full-throttle character without drone at cruising speeds. Valved design provides quiet OE-like operation at part throttle, then opens for authentic performance note under load. Mandrel-bent piping and CNC-formed junctions ensure precision fitment and acoustic consistency. Decibel-tested for street legality in most US jurisdictions. Direct factory fitment. OEM valve compatible. Uses existing Mustang mounting points and hangers. Installation by certified technician recommended. Designed in Tennessee and manufactured in the UK with 40+ years of performance exhaust heritage. Tested on the Tail of the Dragon.
