Are better quality mufflers straight through?

While a lot of people remove them, I really liked the exup valve on my FZ1.
Meant that when starting and cruising around town the bike was quite subtle due to the exup being relatively closed - but really booting it out in the open road and the bike would howl.

Perhaps I should get another exup bike?

I'd like my XJ400 to sound like this:

Any idea what pipe that is?

Nope......but.....
Sounds similar to a Kerker similar to this

I had one on the FZR400 before I toned her down. I have a video with the new exhaust on........will see if I can find one with the old one.
