Bought a used 2022 GMC Sierra and this exhaust system came with it additional from the original owner. He used it once then removed it, all components are included, with the controller unit and remote for the valve system also. This system is by Bullet Performance garage in Dubai, you can take it there for installation. Reach out on WhatsApp or Dubizzle Chat, I am willing to drop it at your location in Dubai or Sharjah.
