So I bit the bullet an booked it in to a zorst shop tomoz. Driving out at 9:30 to Gladesville Quickfit (My mate with his insane wrx got his car there, highly recommended apparently.
Paying $900 - $1100 for a full mild steel painted heatproofed black mild steel mandrel bent 3" system, with a $400 cat and a big oval 3" straight through muffler with a single 3" tip.
I'll chuck some pics up tomoz. This is the absolute last thing that needs to be done now. Hell looking forward to driving it.
Also, snapped this up at the workshop on my iPhone.

Cheers,
