This is the second exhaust manifold that has cracked on my car. The first went out around 45K miles and was fixed under warranty. The first time it was a small crack and produced a ticking noise. This time it's a bit larger and makes the noise of a rumble. It makes the engine sound powerful and my mechanic said it's so small I don't have to worry about damaging the engine (it also doesn't get cold here). So I put up with the muscular sounding engine, but when I have clients in my car, I don't think it's a good thing.

Ticking noise was the exhaust leaking from the exhaust manifold. The dealer replaced under warranty. These things are cast iron and shouldn't crack at this low mileage.
