Do I have the right exhaust hangers on the car?

The exhaust on my car is rubbing my driveshaft pretty good. It was installed in the car before I purchased the car. The car started life as a v6 car. The exhaust is welded together. That makes adjusting it harder than it should be. I am debating just buying a new exhaust system or modifying the current exhaust. The first question if do I have the right exhaust hangers? I was thinking of trying to find another one and drilling out another hole. About an inch to the inside should do it. If they are welded on then I will have to come up with another plan.
