You can't .. some pipes come with new brackets if you buy a exhaust kit
Or you can just google 6" cab brackets and buy them. Their not that expensive 40.00 a bracket .. the thing you should be Is careful is take your take removing the bolts from your old brackets because they screw into rivnuts ans theres a fair chance the rivnuts with spin.. then it becomes a bigger project to swith the brackets

 

They do have reducing tips that go from 6 or 7” to 5”, should upgrade shields though cause they kinda look like sht in my option but to each their own
