Guerrilla Bypass for the Peugeot 508 PSE

Unleash the true sound of your Peugeot 508 PSE
The Peugeot 508 PSE is a masterpiece of hybrid performance and sleek design, but there's one thing missing: the right sound. The factory exhaust is quiet, reserved, and doesn’t do justice to its sporty potential. With the Guerrilla Bypass, you’re in control – switch between subtle and aggressive sound with the push of a button.

Why choose the Guerrilla Bypass?

  • Adjustable exhaust sound – Switch between whisper-quiet and a deep, sporty growl.
  • 100% stainless steel construction – Durable and resistant to heat, moisture, and road salt.
  • Improved flow and performance – Less backpressure, more power, and torque.
  • Plug & play installation – Quick setup without major modifications.
