I got a full custom exhaust from the dump pipe back custom made by my local guy who's done work on all my cars and a few mates cars for only $1130.
3" stanless steel with Xforce 100 cell cat, resonator and muffler.
as for quality and sound its fricken awesome, just ask the boys, Craig, Dale, Iain and Andy they've all seen it up on a hoyst and heard it running.
as my guy said to me even if you buy an exhaust kit you'll most likely have to spend a few hundred just getting it modified and/or mounted onto the car anyway......... so i just chose to support him cos i knew he could do what i wanted.
