What power are you wanting to make. you might find that you will probably end up doing the full system later down the track. twin 2.5" turbo back doesnt make any more nose than the stock one (except at idle and wot).otherwise can just go with a 4" hiflow catco or something. Im sure cats have already been covered somewhere. Link to comment https://www.fordxr6turbo.com/forum/topic/64946-high-flow-cat/#findComment-969156 Share on other sites More sharing options...
