Just pulled a 2005 GT off a Carmax lot with 22K miles on it and I couldn't be happier, plus it still should maintain it's 6 year warrenty!!

My question now is what do I do to it? I'm not looking to race this thing but I want a car that will keep me holding my head up high before I end up buying minivans for the rest of my life. what are some fun modifications I can make to this car on a decent salary to gain some performance as well as keep me busy on the weekend?

all advice is welcome.

Welcome to the forum. Things to add a little performance:
CAI, cat-back exhaust, headers, underdrive/lightweight pulleys, etc. Then there's always a supercharger.

Any thoughts on what CAI to add? Fujita seems to be the best, but I'm no expert.

:00000732: You might try a AEM or Injen cai , i have the Injen . The Injen sri is probably the most popular with Tib owners .
A good source would be 'Importshark' , check the sponsor section on newtiburon.com or check out the toystore at hyundaihouseofpower.com .
For a nice catback at a good price check out ebay 'hyundai obx dual exhaust' , polished stainless & under axle design .
