Milltek Non-Resonated GPF-Back Exhaust | Ineos Grenadier B58 - Burnt Titanium Tips

Description

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. System Specifications • T304L stainless steel mandrel-bent tubing • Direct fitment behind OEM particulate filter (GPF) • Hand-finished burnt/blue titanium exhaust tips • Non-resonated design for closed-course and enthusiast use • OEM hangers and mounting points 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. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
