I have a 1989 Crown Vic with the 5.0L V-8. It has a single exhaust and I would like to put in dual exhaust but I can't find any kits. Does the system have to be custom built or are there kits for it??
You can get a mustang H pipe. I think the rest would need to be made tho. I have custom exaust, 2 pipes all the way back, cats removed. The guys in the 5.0/5.8 section of crownvic.net will help ya with it more.
