Milltek Non-Resonated GPF-Back Exhaust - Ineos Grenadier B58 - Cerakote Black Tips - SSXINE102

Non-resonated particulate filter-back exhaust system for Ineos Grenadier with B58 engine. Direct fitment; OE cutting required at tailpipe junction.

The Grenadier's stock GPF-back system prioritizes emissions compliance at the expense of acoustic character. This Milltek non-resonated system restores the B58's natural tone while maintaining full particulate filter functionality. T304L stainless steel construction with CNC-formed Cerakote Black tips delivers engineered sound character without compromise.

System Specification:

• T304L stainless steel mandrel-bent piping
• Particulate filter-back design (GPF retained)
• Non-resonated architecture for open-throttle character
• Cerakote Black polished tips
• OEM hangers and mounting points
• Direct factory fitment; OE tailpipe cutting required

Hand-finished construction and dyno-tested acoustic tuning deliver measurable improvements in throttle response and full-load driving dynamics. Non-resonated systems are designed for closed-course and track use; street application varies by local regulation.

Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
