https://www.youtube.com/watch?v=T-Hpd0tb7sg this is a 4 piece silencer there is a 26cm and 16cm option - Everyting is 45mm Diamter the end caps fit both versions so if you make the 160mm version and fancy doing the 26cm. then all you need to do is print the 26cm outer and mono core the 160mm has 3 chambers the 260mm has 4. I dont have a db meter but the 160 is better than my donny sumo and the 260 is even better I use 3mm Neoprene to wrap the mono core - I find this helps quieten it down even further - but you could use any sound dampening material you will need to glue in a 1/2" unf mild steel 19mm od weld on found here https://www.ebay.co.uk/itm/272373594628
