ICP BMW N54 Downpipe (E60 535i/535xi)

The ICP BMW N54 Downpipe is a precision-engineered upgrade for the twin-turbocharged inline-6 in the E60 535i and 535xi. By replacing the restrictive factory downpipes, this system improves exhaust flow, reduces turbo lag, and delivers significant horsepower and torque gains when tuned.
