For those that have used Flowmaster 15807 2 1/2" Tailpipes on their 65-66 mustangs, what rear brake line did you run?? Do they work with both the factory single exhaust rear brake line routing and dual exhaust rear brake line routing??? I am redoing my car and getting ready to fill in extra holes in the floor pan (from atleast 2 previous dual exhausts) and want to know whether I should remove the dual exhaust bracket I installed 10 years ago when I converted the 6cyl car to V8 specs...
