GMC Sierra Z71 2018 Used Automatic Gasoline mileage: 170 KM 4WD Modification items for sale, wholesale or retail, and they are clean. Bullet Boit Muffler, original, used for 4 months, clean and guaranteed, and its sound is nice. There is a video of it installed on the car. Blow-off valve, clean. I swear to God, I used it for two weeks and then removed it. It's almost new and has a warranty, but its remote wire is missing. It is present and working. Two right exhaust tips from Al-Hajri, clean, used for 4 months, and guaranteed not to be dented or anything else. Selling for the highest offer. The sale is easy for the serious buyer. The items are clean, and you have the right to come and see them with your own eyes. My sale is easy. ( And do not belittle people's belongings )
