well today i took off my exhaust on a 86 non turbo rx7 because im doing a clutch replacement, and i wanted to hear what the exhaust sounded like header-back, i want to roll with just header-back for a day or two, but does this cause damage to the engine, with no back pressure?

wait are you saying that you want to drive around with an open header and nothing else?
if so BAD IDEA.
washington cops can be pretty chill but you just looking for several tickets.
including niose pollution or whatever it is.

I drove my old 91NA with no exhaust whatsoever from the house to the muffler shop to fabricate a header.
I installed a temporary deflector shield to keep from starting a fire.
It was fun for a few minutes.
Power was down some without the tuning you get from standing wave resonance in an exhaust system.
