ICP BMW N63 Downpipe (550i/650i/750i/X5/X6 – F & G Series)

The ICP BMW N63 Downpipe is a precision-engineered upgrade for BMW’s 4.4L twin-turbo V8, available across both F-Series and G-Series platforms. By replacing the restrictive factory downpipes, this system improves exhaust flow, reduces turbo lag, and unlocks major horsepower gains when paired with ECU tuning.

Made from premium stainless steel with CNC flanges and TIG welds, the ICP N63 Downpipe provides durability, reliability, and OEM-like fitment. Offered in both catless and high-flow catted versions, each includes an integrated heatshield for reduced intake bay temperatures.
