Cats... Gen1 and Gen2 differences?

[NotSoSlowSHO]

Just two quick questions... hoping for a quick answers

Will a Gen 2 cat setup work on a Gen 1?
And are the Gen 2 ATX cats any different?

A Gen II ATX y-pipe will not work on an MTX Gen I. Not sure about the Gen II MTX pipe or if the cats themselves are different.

The y-pipe from a gen two will fit on a gen one, and vise versa (as long as they are both manual transmission equipped). I, myself have put a gen one y-pipe on a gen two with no problems. Side by side and functionally they are the same. This is what I know for sure (but not knowing exact part numbers right now). The gen two ATX y-pipe is different, and although I have not tried myself (and should test as the parts are on hand), it will not fit a MTX equipped SHO (specifically meaning MTX exhaust manifolds with MTX subframe and MTX oil pan).

To sum it up: all MTX SHO y-pipes interchange.
