I'd say the exhaust is probably a Fujitsubo (looks like one) as a lot of the imports come with them - I think they were a JDM factory option.
Also, I disagree with people who are saying to go with the GT pack (apart from the heated seats and cruise control - which CAN be added) as the bose is a pain the arse to upgrade, its easier to get a non bose car as the head unit can be swapped over without any pac-roem thingys and the Cloth seats can be re-covered with a nicer finish for the premium you'd be paying for the GT pack. The only real extra you get with the GT pack is being able to say it's one.
Looks like a nice car though
