TTI exhaust early A-body instillation ?

Getting ready to install my new TTI duel system on my 65 dart and noticed they say you have to remove the RH parking break cable bracket from the flore board. But that is all they say to do. Has any one crossed this bridge before? Do you have the remove the hole parking break system? Kinda looks like you would or the cable would just be hanging there, or rubbing on the exhaust. Thanks for any ideas!!
