Changing the front down pipe today, I had a new one stashed away and when unwrapped it does not have the flex before the cat or the mounting hanger rod, a label says manual trans, I wonder what can the difference be between the manual and auto trans have on the pipe moving, is the mounting hanger deleted to allow for more movement of the pipe to make up for lack of flex joint? Phoned around a bit and dont seem to be able to find an auto box one. I am sure I saw on here a weld in flex joint from ebay but cannot find it now.
