Description
Milltek Non-Resonated Gasoline Particulate Filter-Back Exhaust System for Ineos Grenadier with B58 engine. OEM particulate filter requires cutting for installation.
The 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.
Particulate 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.
- Direct fitment: Ineos Grenadier (all B58-equipped models)
- T304L stainless steel, hand-finished construction
- Mandrel-bent piping for optimal flow dynamics
- Polished stainless tips
- Non-resonated design for open-track character (street legal where permitted)
- OEM hangers used; no modification required except particulate filter removal
Milltek exhausts are manufactured to exacting standards using precision stainless steel engineering, not mass-produced universal systems.
Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
