It has to do with the emissions. Without this on a stock pipe with cats the cats will become ruined and back up too. Do not remove this if you still have the stock pipe. If your going to an off road, many of them have the extension for you to keep it but you don't need it with an offroad pipe or the smog pump for that matter. if you have emissions tests then it would be wise to keep this.
