Just fitted this to my 330ci in race sound level with the sound pipes. It's an outstanding piece of engineering and just the right balance of quieter with no droning when driving normally and loud when pressing on. Possibly a bit much for some in race spec but perfect for me. A really cultured sound and totally different to cheaper alternatives.
Absolutely worth the wait and the extra outlay over lesser systems.
Recently purchased this Eisenmann x2 70mm exhaust in Sport sound for my e46 330i touring and it sounds great bit louder than standard but not to loud to defen me or my family, just needs the middle section eisenmann offer, hope this review helps
