Audi S8 D5 Primary Pipes

Free the twin-turbo V8. Unlock the D5.

The 2019+ Audi S8 D5 Primary Pipes are engineered to replace the factory restrictive catalytic section, allowing the twin-turbocharged 4.0L TFSI V8 to breathe more efficiently and deliver stronger performance across the RPM range.

Available as Race Pipes (decat) or Street Pipes (high-flow 100/200/300 cell), this upgrade gives you the flexibility to choose between maximum flow with a raw, aggressive tone, or a more balanced, road-friendly setup with improved performance.

By reducing backpressure directly from the turbochargers, these primary pipes significantly improve turbo efficiency, resulting in faster spool, sharper throttle response, and increased power delivery. The updated D5 platform responds aggressively to improved flow, unlocking more immediate and responsive acceleration.

Constructed using precision TIG welding and mandrel-bent tubing, these pipes are built to withstand high temperatures while maintaining optimal flow efficiency. Designed as a direct bolt-on solution, installation is seamless with no cutting required.

This isn’t just louder.
This is faster response.
