Looks like a flute. It may or may not be worse than mine, allow me to explain.
On the left is my factory exhaust manifold. It looks like a demonic squid or something, all sorts of tubes intertwined together and then straight into a catalytic converter. This is a great idea in theory as the cat warms up very quickly giving the car great early emissions. However in practice the first cat is too close to engine, it can and will over heat and break down. Especially if anything is causing the car to not run right, or it runs hot. When this happens the broken down gravel/dust parts of the cat swirl around and back into the cylinders through the exhaust valves. This scores the snot out of the cylinder walls, valves, etc etc, causing oil consumption, loss of horsepower, poor fuel economy, poor emissions and eventually catastrophic engine failure.
Great design right? Hence why so many people with the qr25de replace the upper exhaust manifold with a performance header. Not because we're racers, but because we don't want our engines to explode.
