ICP BMW N63/S63 Downpipe (E-Series/F-Series X5M & X6M)

The ICP BMW N63/S63 Downpipe is a high-performance upgrade designed for the X5M and X6M powered by BMW’s twin-turbo V8. By replacing the restrictive factory downpipes, this system dramatically improves exhaust flow, reduces backpressure, and unlocks huge horsepower and torque gains when paired with tuning.

Constructed from 304 stainless steel with CNC-machined flanges and TIG welds, the ICP N63/S63 Downpipe ensures durability and precise OEM-like fitment. Available in both catless and high-flow catted configurations, each option includes integrated heatshielding for superior thermal control.

• BMW X5M (E70) 2010–2013
• BMW X6M (E71) 2010–2014
• BMW X5M (F85) 2015–2019
• BMW X6M (F86) 2015–2019
