Is there a difference in the design of downpipes between the different MY's???

I'm looking at a Tomei DP with metal cat but they're only listed for cars up to applied model D, which I would be an MY04 car.

As I have an MY06 I am unsure whether to order. Have contacted Tomei in Japan about this but still haven't received a reply yet.

Any help would be appreciated.

 

Anybody???
