I am seeing all of these exhaust systems on the 99 and up and the tips are adjustable... On my 97 it isnt.... Well I know SLP makes their exhaust for my car but Borla stinger does not... I am going with one or the other... I would like to be able to adjust the tips and so forth. So can I just buy the hangers for the pipes out the back and do they jus bolt on or what???? Any help highly appreciated!!!!
