BMW X3M & X4M F97 F98 Spool S58 Race Downpipes

Spool S58 race downpipes for the BMW X3M and X4M replace the factory downpipes with 304 stainless pipes that cut backpressure on the twin-turbo inline-six.

Why you need it

The factory downpipes restrict the S58's turbos. Swapping to these frees up flow and, with proper tuning, unlocks over 100 hp. Fitment is spot on for both left-hand and right-hand drive cars.

• BMW X3M (F97, 2019+)
• BMW X4M (F98, 2019+)
• Left-hand and right-hand drive

Features
