I was at Technik the other day and took some pics and a video of an M5 with an Eismann Race exhaust.....WOW. it sounded like a Formula 1 car (in person). The video link has a very good quality sound of the exhaust (put on your headphones). I guess the V10 rocks the planet.
Here are some pics too of the M5 and an Ariel Atom in their garage that they were working on - very nice ride.
