Hi, I recently removed my Arrow System off my RR6 Blade as it was too loud. It sounded awesome but I work shifts and live in the country so it had to go! Anyhow, it's for sale now for €600 or the Sterling equivalent. Great condition. The only issue is some rubber covers on springs have deteriorated. I am in Ireland. I can deliver to Dublin or Rosslare. I can email pics and video for sound. Thanks for looking.
