I would just like to give a shout out to Revan Racing for schooling me on my '13 GT500 and setting me up for success with ordering my ARH Headers! Very knowledgeable and spent a good minute on the phone (even though he was backed up!) ensuring I knew everything I needed before ordering and also made sure I didn't waste money on certain products! They have earned my business and will be the very first vendor I call from now on for my mustang needs. Also very supportive to our military, thanks! :coolman:
