ICP BMW S63 Downpipe (M5/M6 – F Series)

The ICP BMW S63 Downpipe is the ultimate performance upgrade for BMW’s 4.4L twin-turbocharged V8 found in M5, M6, M8, X5M, and X6M models. Replacing the restrictive factory downpipes improves exhaust flow, reduces backpressure, and unlocks massive horsepower and torque gains with ECU tuning.

Constructed from 304 stainless steel with CNC flanges and TIG welds, the ICP S63 Downpipe delivers long-term reliability and OEM-like fitment. Available in both catless and catted options, each system includes an integrated heatshield for superior thermal management.

Fitment (F-Series):

• BMW M5 (F10) 2011–2018
• BMW M6 (F06/F12/F13) 2012–2018
• 2011+ F06 BMW M6 Gran Coupe
