Milltek Road+ Particulate Filter Back - Ineos Quartermaster B58 - Brushed Titanium Tips - SSXINE139

Milltek Road+ Part-Resonated Particulate Filter-Back exhaust system for the Ineos Quartermaster (B58 petrol engine, from 2024). Designed to restore performance character lost to the OE gasoline particulate filter while maintaining a refined, engineered tone with improved sound dynamics.

T304L stainless steel construction with mandrel-bent pipework and brushed titanium tips. The part-resonated design targets OE resonance points to eliminate drone while delivering a distinctly more vocal full-throttle note than stock. Direct factory fitment using OEM hangers-no modifications required.
