If you have an exhaust leak, it could be anything. Most likely, you did nothing wrong. Check the exhaust manifold gasket. Also, make sure the catalytic converter isn't plugging. If the vehicle is outside, have a helper place his foot over the end of the exhaust. That will build back pressure and hopefully help you find where the leak is located. NOTE: I'm sure you already know this, but don't run the vehicle in an enclosed area. Make sure you have enough ventilation.
