The Si rear exhaust mount is a little bit farther out/back than a Grandes. So I punched a hole to sneak a screw in the subframe and this pipe fits well on one of my Vespa Grande Deluxes…to be honest I would love another one of these pipes she rippppppsssss and too boot the black paint has a metallic flake. I’ve never seen that on an exhaust before.
Give me some of that Egg Poachaaa!!
