I have another zs 180 with stainless steel system and its a bit too noisy for me if i'm going a distance. I want to keep my everyday zs standard unless there is a stainless steel backbox thats not too noisy! any suggestions?
if you get a custom long life one made up [about the same pound notes as a standard one] you can have it as loud or as quiet as you like. they just stick more wadding in. Mine is nice and burbley at low revs and surprisingly quiet on a motorway journey.
