This is a copy of the famous Akrapovic slip on silencer made in Italy, i bought it from a mate who had it from new but never fitted it. I have put it on my bike for picture purpose and taken it around the block to hear it. It sounds great and as you would expect and much lighter. The quality is surprisingly good, with all fixings and links to existing downpipes well. There is a tiny dint under the silencer, cant see unless yr kneeling down underneath the bike. Fits all bikes from 2013 (LC) onwards, not a bad accessory at the price considering originals are £750 £250.00 ono plus postage
