I have the same setup with an Eisenmann Race. I first had the x-pipe with no resonators. The drone and rasp was insane...I then got the resonators put on...and wow what a difference. I met up with dogears. He was nice enough to let me drive his car a bit. With an Eisenmann Sport there was no drone at all. It wasnt Raspy.. I would call it Higher Pitch. Although, after driving a bit I really fell in love with my Eisenmann Race Setup. There is a bit of Drone but I dont mind it. As for the sound of the Race..The fucking car screams. Its not Raspy at all. Its a sound in its own class. I was at the Johnny Dents car show and a few people asked to hear the car. Everyone seemed to love the sound.
Both the Race and Sport Exhausts sound amazing. It all depends on how loud you want your exhaust to be and if you dont mind some drone.
