Audi B9 / B9.5 S4 & S5 3.0T High Flow Race Downpipe

The Palenon Performance racing downpipe for the Audi S4 and S5 3.0T reduces backpressure for faster turbo spool, more horsepower and torque potential, and a more aggressive exhaust note with pops and bangs.

Why you need it

A high-flow design with a fat section maximizes exhaust efficiency right after the turbo, making it a strong base for performance and track-focused builds.
