Hi all. Is there anyone in the yorkshire area that have a e55 with modded exhaust as i would like to hear a few before i make a decision as to how to go about it. I will probably get it done from acid at msl. The sound i want is not that raspy farty sound. Its deep warble i want without it sound too drony inside.. similar to the new 63 biturbo. (Sounds insane but at the same time refined).
