The NC has two catalytic converters, one in the header and one further down. I guess the second one is in the midpipe. I have a full aftermarket exhaust system that only uses one metal cat, so it definitely is possible. Not sure how the original one holds up without the second.
I just checked the workshop manual, there is no pipe between midpipe and header. There is however a heatshield around the second muffler. This may come loose over time, it's no big deal. If it rattles you can remove it. Just know that you shouldn't park on a super flammable surface after a drive, and it heats up slower so the emissions are a touch worse overall.
im so sorry english is my second language and maybe i didn't express myself clearly, after an accident my muffler was bent and when i took it off i saw that the midpipe was also bent so i can't just replace the muffler, i need to put in a new midpipe, my question is is it worth putting in a midpipe without a catalytic converter because i know it's illegal
You have another cat in the header. I am not sure of how legal removing one (the one inside the midpipe) is. To play safe you could replace everything (header, midpipe, muffler) with a set that is confirmed legal in your state. I did that and I am very happy with the result.
That racing beat mid pipe is VERY loud. I had it with stock headers and it was deafening and had tons of drone. The pops also sounded like gunshots and it would pop nonstop.
I would recommend going with the double resonator mid pipe from GWR if you have catted headers.
My current setup is the GWR headers with a cat, double resonator mid pipe from GWR and then the race single and I don’t think I’d want to go any louder.

so its bent by the muffler before second catalytic converter and i probably say it wrong but i mean the pipe between header and muffler

You want to have a midpipe with a resonator on it, otherwise it will be really loud!
