Decat testpipe 8-9 to 4?

[meka]

Will a decat test pipe from an 8-9 fit on my evo4?
I have stock downpipe, stock cat, and then fujisubo cat back.

The pipe has bung for O2 and my stock cat just has cat temp sensor I think.
thanks

4-6 Will fit
7-9 have different flange angle I believe so it won't line up

Angles the same, bolt patterns are different.

thanks. It was confusing since they look identical in so many photos
