(Not exactly the most economical).

(This is my 2011 35i that replaced my 2001 3.0i)

I do love the exhaust note. Wife calls it exhaust therapy. I agree.

Here's another where I rev twice and open the exhaust flap for the second rev.

You'd think you can modify the 3.0i exhaust to match the 35i. You won't get quite as burly of a note but the first video above is just idle and it's the same basic engine when turbo not spinning. Wonder what it would take to retrofit e70 exhaust to e53. (thinking junk yard grab).

that does sound nice, I have a theory now that my whistling sound might be a crack in the valve cover gasket which makes me want to replace this as I haven't done it in awhile, have you heard any reviews on the aluminum ones?

I'm leaning towards just going the BMW OEM, those usually already come with the gaskets and such installed on them too if I recall correctly.
