Milltek Sport BMW X3M/X3M Competition S58 Downpipe Back Exhaust System completely transforms the X3M's driving experience with enhanced sound and a noticeable performance gain. The system bypasses the factory OPF filters for increased airflow and reduced back pressure. Please note: This system will require a stage 2 ECU software or OPF cables.
Choose between a resonated system and a non-resonated system along with a wide range of tip styles. The resonated system is quieter than the non-resonated system - sometimes preferable for daily driving. The non-resonated system will have the best performance gains.
Designed and manufactured in the UK!
