I think finding the 'perfect' sound for this car is virtually impossible. When you get a great axle back note, it's fine till 3k rpm then there's drone in the most useable rev range. You pay another $600 for a hi flow catted front pipe and that does very little except throw the tone out again. Then when you add headers, especially uncatted, the whole lots virtually uselessly loud and you have to resort to the OEM rear muffler. That's precisely why you never sell them or get rid of them.
My theory after probably spending near on $4k on exhaust bits is work from the front back. Headers, OP, hi flow front pipe, larger resonated midpipe (to kill the decibel increase from the headers), and AB last. The OEM rear muffler will handle the noise increase of each upgrade till you finally get around to thinking about changing it.
I think with your setup (can't remember if you have a Hi-flow front pipe or not) like mine leaves very few alternatives except replacing and increasing the diameter/length of the resonator which is obviously what you're doing. Can probably go an extra 300mm length wise but not sure about side clearances.
I'll be very interested, given I'm in a similar predicament, to see how you go.
Good luck with it...
