i was on the focus central web page and was looking at the cats and they said that you can place the their cat where the stock flex-pipe was when using a race header. so my i was wondering if anyone has done this
I know some people have done that. There is an important consideration when doing that- find out if it is legal in your state to move the cat. Otherwise you might have to reinstall stock items to pass emissions. If it will be a problem in your state then just put the race header on and swap it out for stock when you have to get the car tested.
