Hi Mate,
Those pictures rock, loving it in red. I hear what you're saying about Auckland traffic, I was back there last month, can't believe how bad its got. Also impressed by how dodgy looking Papakura has got as well. Wouldn't leave the XR6T lying around there.. get a bit too much attention from the cuzzie bro fraternity.
As for exhausts I'm considering getting a rage system from Christchurch. They are just under £300 for your car plus another £50 p&p through partsco.com. Just going to get the headers stuck on first though.
