ICP BMW N63/N63TU Downpipe (F/G-Series)

The ICP BMW N63 Downpipe (F/G-Series) is a high-performance upgrade designed for BMW’s twin-turbocharged V8 engines (N63 and N63TU). By replacing the restrictive factory downpipes, this precision-engineered unit dramatically improves exhaust flow, reduces turbo lag, and delivers substantial horsepower and torque gains when paired with tuning software.

Constructed from premium stainless steel with CNC-machined flanges and TIG welds, the ICP N63 Downpipe is built for strength, reliability, and an OEM-like fit. Available in both catless and high-flow catted configurations, each version includes an integrated heatshield for superior thermal management.
