Hold-Off if you have a 2005
I was talking to the guys at Corsa who also told me that while the 2003-04 model will technically "bolt-up" to a 2005, it is not properly tuned for a 2005 and sounds very harsh with a whistle at full throtle. So, they are redesigning and retuning a 2005 version. ETA: 2 months.
