Audi S5 B9 Primary Pipes

Free the V6. Unlock the S5.

The 2016–2020 Audi S5 B9 Primary Pipes are engineered to replace the factory restrictive catalytic section, allowing the turbocharged 3.0L TFSI V6 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 turbocharger, this primary pipe significantly improves turbo efficiency, resulting in faster spool, sharper throttle response, and increased power delivery. The S5's turbocharged V6 platform responds aggressively to reduced restriction, unlocking more of its true performance potential.

Constructed using precision TIG welding and mandrel-bent tubing, this pipe is 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 boosted performance.
