OEM particulate filter requires cutting for installation.\u003c\/p\u003e\n\u003cp\u003eThe Grenadier is engineered for off-road capability and utility, but the factory exhaust dampens both engine note and road performance. This non-resonated system unlocks the B58's potential, delivering a purposeful tone while improving throttle response and driving dynamics. Hand-finished T304L stainless steel construction with mandrel-bent piping and polished exit tips.\u003c\/p\u003e\n\u003cp\u003eParticulate filters (GPF\/OPF) have been standard on many Euro-spec engines since late 2018 to meet emissions regulations. These filters significantly reduce exhaust sound and restrict flow. Milltek's GPF-back design compensates for this acoustic suppression, restoring full-throttle character while maintaining OEM emissions compliance for street use.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDirect fitment: Ineos Grenadier (all B58-equipped models)\u003c\/li\u003e\n\u003cli\u003eT304L stainless steel, hand-finished construction\u003c\/li\u003e\n\u003cli\u003eMandrel-bent piping for optimal flow dynamics\u003c\/li\u003e\n\u003cli\u003ePolished stainless tips\u003c\/li\u003e\n\u003cli\u003eNon-resonated design for open-track character (street legal where permitted)\u003c\/li\u003e\n\u003cli\u003eOEM hangers used; no modification required except particulate filter removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e Milltek exhausts are manufactured to exacting standards using precision stainless steel engineering, not mass-produced universal systems. \u003c\/p\u003e\n\u003cp\u003eDesigned and manufactured in the UK with 40+ years of performance exhaust heritage.
