Thanks

Measure it and that should tell you. Most Nissan cats are the same length and bolt pattern. I would think the 3.0l would have the same ones.

I was inquiring as I had a high flow cat on my 5th gen and I was considering selling it to a 4th gen owner. However I have compared my old 4th gen test pipe to the high flow and it seems to be about the same length so in theory it should work. The problem here is that the high flow cat actually has no flanges and it works with clamps instead, where as an actual oem cat has flanges that are set on different angles from each other. So either way, I am not looking at a plug and play situation here on a 4th gen....flanges must be welded, vice-versa.

the answer is yes.

95-01 is interchangable.

would a test pipe built for a 4th gen fit a 5.5?

95-96 have a o2 bung in it so I would avoid those unless you wanna put a bolt in it.
