09+ Ralliart Exhaust specs
 

I'm looking to get this muffler for my 2010 Ralliart (http://www.ultimate-racing.com/Produ..._Muffler.shtml). I'm getting it from a wholesale dealer and they need to know inlet/outlet sizes. Does anyone know the dimensions of the inlets/outlets for the cat-back section of the exhaust or where i can get a diagram of the system itself.

thanks
