Supersprint LH Turbo Sports Cat Pipe for BMW M5 F90 - Part No. 525241

Unlock sharper response and a richer soundtrack with Supersprint’s left-hand turbo sports catalyst for the F90 M5. This high flow cat section replaces the restrictive factory front pipe on the left side, boosting exhaust velocity for crisper throttle, faster spool characteristics and a deeper, more assertive tone while retaining a catalytic element for a refined, premium feel. Built by Supersprint for accuracy and longevity, it is a precision fit on the F90 platform and integrates cleanly with the original system.

Why enthusiasts choose this Supersprint sports cat

• High flow catalyst on the left-hand turbo side to reduce back pressure and improve response
• Noticeably fuller exhaust note under load with civilised manners on cruise
