I have the full Supersprint (Race) system on mine and the static noise test hits 107dB (so absolutely zero chance of getting on track at Bedford with it). It was no bother at all with the standard back box on (I just didn't like how raspy it sounded). The system is a few years old, so probably repacking it would bring the noise down.
