As this is a'race' silencer it is not homologated for road use, and does not meet legal noise requirements, but it is supplied with a removeable DB Killer which significantly reduces noise when fitted. We are one of only a few official retailers for Arrow products and we are also one of the biggest and best known specialist motorcycle parts distributors in the UK. We have been supplying high quality motorcycle parts to thousands of motorcycle businesses across the UK for over 30 years. This will be longer during August when Italy closes for annual holidays and also Christmas, for obvious reasons.
