Customer Review: (see review/s)
  • I ordered my headers one day and recieved them about 2 days later. They were easy to install and the fit was an exact match to my truck. The only problem I had was the cheap made gaskets for my headers. After install I had an exhaust leak that I couldn't get rid of.
