Just installed my set of Stromungs yesterday. I've got only about 40 minutes of top down seat time with them. They sound very nice. Time will tell if I wish they were a touch quieter, my Miata before my //M was supercharged and somewhat loud. The last 16 mths with my stock exhaust were a nice change, but I really missed hearing my car. I put a good amount of time (and some $$) into upgrading my stereo and I hope that was not all for naught. Maybe I just should have hacked my iPod to mix in the soundtrack from someone else's Stromung's a-la an M5!
