Question What makes the 230K engine sound like an underwater lawnmower?

The exhaust sound at cold startup is pretty weird, but it's just generally an odd-sounding engine. I have even seen that noted in magazines.
Anyone know why?

I think it's mainly the exhaust system design and the supercharger.

Thanks, Dave! The sound of the coupe does seem improved over the original SLKs.

On cold start it almost sounds like it has an exhaust leak. Then after the warm up cycle it sound quite diffrent. I have been told that when cold it dumps air off the SC into the exhaust to help warm up the cat.

the alternative

I would much rather my car sounds like an "underwater lawnmower" than a bumble bee with one of those "fart cans" that all the imports have. I actually like the sounds of my car when I get on it. When you consider the alternative sound its not so bad now is it?!
