Nick, in changing out the 4 incredibly heavy original silencers for 2 custom ones, the weight saving is really very significant, I'd guess between 30 & 50kg
I have the old exhaust system in the loft, it is heavy but not sure of the exact figure as never weighed it. Unfortunately I never handled the Librands system before installation, so no idea how much that weighs in comparison!
Any weight saving is good though.
