GMC Sierra Z71 2014 Automatic Gasoline 4WD Peace, mercy, and blessings of God be upon you. Please read the advertisement before. The car I bought it with a custom muffler and full exhaust system. From the Bolt brand and rocket outlets according to its owner. I want the original exhaust system. Whoever is interested can give me the original exhaust system and take this one. Note that there is no device or remote, only the muffler and blue hoses. Thank you.
