Opinions please

[Matt]

I'm looking to do something with my exhaust.
Those that have heard it will no its stupidly loud.
I have a straight through middle section and a cheap big bore back box
They are joined by sloting the back box into the middle pipe.

My options are

1. Somehow make a standard back box fit the straight middle.
2. Fit a standard middle, and weld a flange on the bore backbox
3. Complete standard setup.

I kinda want the sound. But not as much as I have now.
Big bore exhausts have the rep for sounding shit on there own
What will a straight through with a standard box sound like?

Oh btw I've got a 2.0 xsi btw
Opionins please
