The Milltek Sport Non-Resonated Cat-Back Exhaust System with GPF Bypass is designed for MINI F56 Cooper S and JCW LCI models fitted with GPF/OPF.
 
This system completely removes the front silencer and bypasses the restrictive GPF section, delivering a significantly louder, more aggressive exhaust note while improving exhaust flow and throttle response. As a direct replacement for the factory system, it installs cleanly with no cutting or fabrication required.
 
Constructed from 304L Aircraft-Grade stainless steel, this exhaust is built to withstand harsh conditions while maintaining long-term performance and sound quality.
