WRX/STI exhaust query
Have got an import 96 wrx with a standard exhaust...back box is numbered MMFA5.
Have also got an STI centre section and back box. The centre section has not got a cat so I am thinking I should use it. The back box looks similar to my wrx one...i.e. the twin exit, however it is numbered MMFA2. Does this mean it is any different as regards better flow etc.
