The main obstacle is the steering shaft. You may run into other issues with the crossmember, or the floor, or the shock towers, as mustangs have more room in all those areas, but you won't know that until you get them installed and you can see what clears and what doesn't, but the steering shaft is the main problem, and the only way around that is to do the steering shaft mod, which some people don't like because it gets rid of the collapsible steering column, which could cause injury in a severe accident.
My car still has the stock MarkVIII exhaust manifolds on it. The only other option that is a direct bolt-on are the Kooks 3/4 lengths. Years ago a company named ART made real long-tubes for the MarkVIII, but they haven't been in production for probably about 10 years now, and good luck finding a used set.
