My brother in law just traded in his 2008 gmc and kept the mini max and cord. It's about 2years old and works as it should with paperwork and box. Not looking to take advantage of the situation of h&s but have to put a price so I'll say $500. Also have complete factory exhaust with about 40k miles ( if legal to even sell). Also have a new white tailgate for the same truck if interested. Thanks Jason
