Non-resonated particulate filter-back exhaust system for Ineos Grenadier (all B58 models). OEM particulate filter requires cutting for installation.
The Grenadier's factory exhaust prioritizes emissions compliance over driving character. This Milltek GPF-back system opens up the B58's acoustic potential, delivering engineered tone and measurable sound improvement without resonance drone. Hand-finished T304L stainless steel construction with burnt/blue titanium tips.

- T304L stainless steel mandrel-bent tubing
- Direct fitment behind OEM particulate filter (GPF)

This GPF-back design compensates for the sound-dampening characteristics of modern particulate filters, restoring the B58's natural exhaust note while maintaining precision fitment and durability.
