Milltek Non-Resonated GPF-Back Exhaust - Ineos Grenadier B58 - Burnt Titanium Tips - SSXINE104

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)
