So, I was driving out of a car park the other day and BOOM, this metal slug in the floor ripped the flexi in half on the downpipe so I need a new one. Just for the part Audi quoted £250, Euro Car parts don't do one, so I was looking at getting a new flexi and welding it on, or buying a second hand exhaust off eBay, but I have the opportunity to add a de cat downpipe, so a few questions. Do I really have to unbolt the drive shaft to the rear to remove the downpipe? I just cannot seem to get the exhaust out! If I put on a de cat from ebay like this one, will it fail the next MOT, as I saw somewhere that says, if your car originally had a cat, it must have one to pass the MOT now, and would if fail on emissions? If I do go down the welding a new flexi on, Anyone around Bournemouth want a few quid to weld it on? Its a 99V turbo Quattro, currently mapped to 212BHP. Thanks.
