Introduction

In this installation guide we have provided step by step instructions to setup, remove the OEM exhaust, and install the 27WON Performance Exhaust.

Advisory:

  • Working under the vehicle requires a safe and sturdy location for the vehicle to sit on jackstands
  • Use the hydraulic jack to raise the vehicle and the jack stands to support the vehicle in the OE recommended locations
  • The exhaust piping will be hot after recent vehicle operation. Allow the vehicle to cool or use a fan to cool the exhaust piping before working on the vehicle
