Has anyone installed a Hartge muffler?

I have a 1994 525i and want a sportier sound, not really looking for a perfomance increase. What type sound does the Hartge have at idle and at WOT?

The hartge muffler, at least the older ones, were made my supersprint.

Here's a video of supersprint on an e39 540
