Mr Fergie

Thanks

does anyone else own this model that's come across this issue ?

I have recently brought a 2009 WRX s hatch, the car is one owner 54k all standard as far as i know ,when I drove the car initially it seemed to have a very quiet exhaust considering its got a prodrive back box .when i had it up on the ramp this week i measured the exhaust bore size from the cat to centre section its 2.5 inch dia ,The centre section and muffler pipe is only 2.25 inch dia before joining the tailbox section which then goes back to 2.5 inch dia - the centre section has subaru stamped on it so its genuine is this normal for this model.? is there a a way of deleting the centre box with a straight through pipe to match cheers in advance
