I was driving the other day and noticed brake sounded louder, I come to find out that the one flange that you attach to the exhaust and then the brake rotted out. Also along with my whole aluminized exhaust #@$%!. It also seems apon further inspection that brake housing is corroding and falling apart is this normal? the questions I have are as follows the flanges that bd supplies can they be found in stainless? I am about to put a stainless exhaust on and wanna get the stainless down pipe as well. will that down pipe work with twins , and also has anyone experienced this with the housing falling apart maybe its supposed to happen but fig i'd find out thanks... .
