Get the leak fixed.

There is no more leak. There has been for the last, who knows how many miles. Since i bought the car. I drove it 5k miles with an exhaust leak spending hundreds trying to run it down along the way.
As of yesterday I have a new x pipe and no exhaust leak. This is when the running rich problem first appeared.
