We ride bikes, just like you. With over 50yrs of experience in road, dirt, racing & tuning... sometimes crashing, we know what works! With our experience and knowledge we have developed Screaming Demon & Musarri Exhausts to offer the best sound, performance, quality and fit that leaves many bigger names wondering what they missed. More then just a name, we build exhausts that will literally outlast the bike they are fitted too. That's not a pun, its a fact.
