BMW X5M F85 Catless & High-Flow Catted Downpipes — S63 4.4L Twin-Turbo V8 | 2015–2018
YPG Motorsport catless downpipes for the BMW X5M F85. Direct bolt-on replacement for the factory catalytic converters on the S63 4.4L twin-turbo V8. The X5M shares the same hot-vee S63 engine as the M5 and M6 — removing the factory cats delivers immediate gains in turbo spool, mid-range torque, and exhaust volume. The transformation in sound alone is worth the install on the X5M platform.
Available in catless, 200-cell high-flow catted, and 400-cell GESI catted configurations.
