No offense to who ever's wrx is in the first clip but that is the worst sounding one I have heard...
I might be just used to hearing the: thud, thud, thud, thud noise the the engine makes... the second clip is a little better :-)

I like the boxer sound :-)

The Maxim Works header completely eliminates the boxer rumble. First hand experience. Whichever header the car in the soundclip had, it sure wasn't a "true" equal length header.

... and is the most expensive header available for the WRX/STI

Acutally, no, it depends. I got mine new for $1000 shipped.

Now, an Aqua, or Zerosports, or Syms header. Those are more expensive. And to top it off, the Zerosports and Aqua headers don't even have integrated uppipes like the Maxim Works one does. So you'd also need to factor in the cost of an uppipe for those.
