Just got my hands on a '24 stock Nismo mid pipe and muffler to replace the suitcase muffler that came on my car. Wow what a difference. The car actually sounds like it should now with the manual midpipe (no resonators) and auto muffler.
I didn't expect all the happy little burbles transitioning to decel, and the accel note has a lot more racey pitch. There is some slight interior drone (I have all the sound enhancement/cancelation turned off) bit it isn't bad at all. It's more that you can just actually hear the engine now. Good stuff. Hopefully wife likes it and I don't have to put the resonated midpipe on.

So you have a manual and kept your mid-pipe, but swapped to the auto exhaust?

From the service manual if anyone's interested, manual and auto:

I love the exhaust on my 26 Sport model, it sounds perfect, I suspect it is quieter than your car as mine has the factory resonators. That was a cool mod. that you did, these exhausts are really nice and well made , good sounding !

Yes exactly. The least muffled factory parts combo. It sounds so good. There must be someone on the engine team that meant for it to be a thing.
