Default 2007 Subaru Impreza 2.5i Exhaust

I have a 2004 Subaru WRX Wagon and a 2007 Subaru Impreza 2.5i. I am going to be getting a tomei for my wagon and UEL headers for my Impreza. I am wondering if I can take the HKS Hi-Power catback I have now and install it onto my 07 Impreza 2.5i. I will be putting the Tsudo headers and hi flow cat on the 2.5i. I know I would prolly have to modify the flange on my HKS to fit the Tsudo from 3" to 2.25".

The cat back will mount onto the car but it will be a couple of inches short of the cat pipe.

Is the Impreza a wagon too or a sedan?

The flange should just need to be clocked or rotated to match the Cat-pipe.

I ran a modified WRX catback at one point, and the length was fine, but the orientation of the flange was what needed changing.

Sedan or Wagon, the exhausts are the same.
