Is it me, or is the exhaust louder when the Sport button is pressed?

Maybe it's just more noticeable with the DLV exhaust?

Funny, I didn't notice it on my 3.0i?

Also can barely hear the sound gen on this one compared to the 3.0i?

I haven't got a link handy but I've seen the percentage change graphs displaying the changes-the engine makes no additional power, it just feels like it :P
