So the meathead i rescued my 01 disco from didnt tell me he ripped the cats off it...so now i need to put new ones on issue im having is i can't afford the $400+ for a oem direct bolt on....anyone have a good recommendation on what i can use? Maybe universal cats and just have new 02 bungs welded in since i need to replace the whole exhaust.
