Yeah, Im a big believer in loud pipes saving lives. I could see some riders with music jacked up, not paying attention and wouldn't notice if a hazard is around them.I've done it a few times... The term 'Loud Pipes Save Lives' springs to mind though: If everyone had earphones in with the music jacked up, loud pipes most definitely wouldn't save lives! So in general I avoid it, I'd rather have all my senses focusing on the task at hand haha!
