I know you're from Australia but that ^ was confusing as hell. lol. I'll sum it up for other guys with more knowledge than me on this issue.

He has Tomei headers on his 03 DE engine and is going to be getting a newer Z, either a 06 Rev-Up or 07 HR Z and was wondering if his Tomei headers will bolt up to either of the newer engines. And he has Sard free flowing cats as well.

There was a thread a few weeks ago talking about this interchangeability of headers and the answer is yes if you use the hfc/cat/tp that will bolt up to the the headers.

yeah but how the effect towards the performance?

I have them on my DE engine and it performed really well against DC headers. As for how they compare to the HR equal length headers, don't know, but I will guess better.
