When you put the pipe on, just make sure there are no washers welded at the ends. Leovinci may do this as ninja does to restrict their pipes in accordance with French laws, so you have to remove them.
I say try it, unless someone here has actually used it. The Sim Exhaust sucks. I bought one before I knew how pipes work and it was a mistake. The expansion chamber is just WAY to small.
I would recommend getting a performance variator. It makes SOOO much difference. Good luck.
