Here is the link for the Data Basstar True Dual Exhaust.
http://www.Intensepower.com is a great place to buy from, everthing that I have bought for the car has been through them. If your looking to spend arond 1,500 and you dont want to wait 4 to 6 weeks another good exhaust to think about is the GReddy EVOTT Turbo True Dual Exhaust. My best friend has this exhaust on his Z and let me tell you, it is amazing. looks and sounds great. Sure its meant for FI because of how big it is but its still a great exhaust. Thats my two cents. keep us updated on what you finially decide.
