2021 bmw m340
So since the 2021 340 can not be bench flashed yet to tune it , is it safe to run a downpipe, charge pipe & cold air intake without stage 2 tune ?

Why would you replace the charge pipe? The air to water intercooler and fixed position of the pipe make it highly unlikely to have the issues the N55/N54 engine had.
You can run a downpipe without a tune, but you will get a CEL. Cold air intake is not a problem but it would only help with intake sound, not performance. |

I just purchased the Dinan intake. Not buying it for whatever gains they posted. It's more for under the hood eye candy and the improved sound. If there happens to be an increase in hp/tq I would consider that a bonus.
