I have a gdi/piper recessed system fitted and would like to see or know how other people have fitted theres. When i took mine to the garage to have it fitted they welded an L shape piece of metal on to the bracket of the backbox because they said the original design of the exhaust would not fit the rear hanger, so obviosly i was a bit concerned but its done now so want to see if its the garage whose cocked up or wether it is a design fault. Thanks
