So I measured the exhaust port. It is 16mm. Does anyone know what exhasut kits I can buy that will fit it? It is the 2 bolt, sort of oval shaped flange ones. If you know what I'm talking about, I would like to get a different exhaust, this pan style is just too restrictive. Also what are the common sizes for puchs since I will most likely try and use something that isnt hard to find, if possible.
