I can't really speak for the 07s, but the previous generation also has a lot of soot buildup on the exhaust because it runs rich, which keeps cylinder temps lower and prevents detonation, I believe. It's a bit of extra insurance on a forced induction car, but not totally necessary. The soot'll just wash off with a bit of soap and water, usually with no scrubbing required.
