Currently got a Cobra backbox on my otherwise totally standard Blob eye WRX, thinking about getting the cobra unresonated mid pipe to go with it, will this change the sound/make it louder at all though?

If you will get middle unresonated center pipe,your sound will be louder.

Hi chap, only a month ago I did the same thing although I do have a decat up-pipe to. Its a bit louder with the straight through centre section and you get the odd pop at the the back but that might be because I've got the up-pipe done.

The only extra part I needed was a cone gasket to get a proper seal to the cat pipe.
