D.I.Y pipe. any suggestions?

Has anyone looked inside a stock Aus pipe before?
heres some pics.
I have a couple of thoughts on this.
1 the exhaust comes to the back of the pipe then goes back through the two smaller holes, then up and out that pissy little pipe out the back. should i drill holes in the back plate to let some gas out before it goes up and around, or drill holes in the out let pipe to let gas out prior to going up and around,
2 put just a bigger outlet pipe on? you can see a collar on the outlet pipe that fits into the large hole in the exhaust, should i, get pipe same diameter as collar and fit outlet, or enlarge that hole and fit bigger outlet?
original pipe internal diameter 26 mm collar diameter 30. would 4 mm make that much difference.
your thoughts.... and don't say 'just go buy a pipe'

Have you thought of taking out the backplate all together and leave the outlet pipe the same? If your metal fab skills are good, I would turn it into a straight through design.
Doesn't it just piss you off?

here is old pipe first
here is new
looks like bought one. i'll let you know how she goes.
the outlet was 26mm and is now 38mm does this raise jetting issues?
