Hi All, I just got my Leo vince slip ons and I'm sitting in my living room doing a dry fit. Two restrictor plates came in the box but they're not in the directions. Do I need to put these in? They weren't in a parts bag. They were between two pieces of the cardboard packing material. Are they even supposed to be in the box? Please help?
Ignore them. They are parts if you are installing the pipes in some European countries with noise regulations.
