My Echo Exhaust Leak in Front ? - Toyota Yaris Forums

You obliviously have an exhaust leak at the front. The most common culprits would be the exhaust manifold gasket (#2), a crack in the exhaust manifold (#1), the manifold to mid pipe gasket (#6), and a hole somewhere in the mid pipe (#5). Take a look under the hood behind the engine to get a look at the exhaust manifold to see if the leak is there or further down the system. The exhaust manifold has a heat shield (#4) which you might want to take off to get a better look. If the leak is in the engine bay those fuses will eventually get into the cabin so I would get it fixed sooner rather than later. With a very loud exhaust you also run the risk of getting a ticket for that. Here's a diagram of the exhaust system on the 05 Echo HB:
