I have a 1998 MPI with an aftermarket exhaust (which it is escapes me) and was thinking about cat deleting it with the bolt in part you can buy for the sound and possible miniscule power increase. My question is will doing this mess up anything in not thinking of like any sensors etc?
Thanks!

yall have put it back on for mot's or it will fail ….. only the spi/carb cross over years can delete it at some mot stations .

Ahh ok, sensing not much point then, sounds like it just makes the noise more 'honda ricer'-esque, not nice!

Removing it does let the exhaust sit higher

You'll gain very little by removing it.

That is a little issue that I am having but my understanding is the replacement tube has the same flanges (assuming it's not just straight welded) which is what fowls?

Some aftermarket or reproduction cats have the flange holes at a slightly different angle to what is needed, so the wide body of the cat scrapes.
Personally id fit a pre cat exhaust and if your tester says anything just say you bought the car with that system fitted.
Any pre MPI mini will pass without a cat.
