3" centre section on Blitz NUR Spec?
 

I've got a Blitz NUR Spec 3" system on my sti 5 along with a standard downpipe. The centre section reduces from 3" to 2.5" to connect to the downpipe.

Now I want to go 3" all the way. I've got a Hayward and Scott downpipe ready to go on but what should I do with the centre section? Is there another Blitz center section I can change to or am I better getting a 3" flange welded on?

Any advice?
