Bentley Flying Spur W12 Primary Pipes

Free the turbos. Elevate the grand tourer.

The 2019+ Bentley Flying Spur W12 Primary Pipes are engineered to replace the factory restrictive catalytic section, allowing the twin-turbo 4.0L V8 to breathe freely and deliver its full performance potential.

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 across the RPM range. Upgraded downpipes on the 4.0L V8 platform are known to deliver noticeable gains in power and response by improving exhaust flow and reducing restriction.

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

This isn’t just refinement.
This is performance unlocked.
