Yea the 2008 are for the HR motor which are the ones I asked the seller for and the 03 are for the DE motor. I read they are fitted for the two types of motor.
The hr has different headers that have a different bolt pattern at exit, thus a different bolt pattern on the cat. I THINK you can bolt hr headers and cats together on any 350z, but I can't remember for sure whether the head has a different pattern for the header.
