Does this fit my car?

This product is compatible with the following models and year ranges:

Audi RS4 B9 (2018-2019)
Audi RS5 F5 (2018-2019)

Designed and manufactured by Scorpion’s experienced engineering team, these 70mm (2.75″) downpipe exhaust systems are tailored specifically for the Audi RS4/RS5 B9. By replacing the standard exhaust downpipe, it optimises exhaust gas flow from your turbocharged engine and helps enhance performance for a more involving driving experience, all while maintaining a clean, OE-style fit and finish.


De-Cat: Maximises exhaust flow and volume with a straight through section. This is intended for off-road use only.


How Does It Improve Your RS4/RS5?

A downpipe upgrade improves your car by reducing exhaust back pressure at the turbo outlet, allowing the turbocharger to spool faster and operate more efficiently. This results in noticeable gains in horsepower and torque, sharper throttle response, and improved mid range pull, especially when combined with ECU tuning.

In addition, a high flow sports cat or de-cat downpipe enhances exhaust sound, delivering a deeper, more aggressive tone under load while reducing heat retention in the turbo system. On tuned setups, it also helps maintain more stable boost and exhaust gas temperatures, supporting safer and more consistent performance under hard driving.

Built to withstand year round UK conditions, all Scorpion systems are designed for long term durability and feature a lifetime warranty*.
