Driving Around With A Leaking Exhaust Manifold Cause Any Damage Apart From Sounding Horrible

Gday, posted in general maintenance but didnt get a reply

I have a leaking manifold due to one of the holes were the studs screw in being threaded and not having a stud in there. It never was a problem for about 9 months but now i believe it has warped the manifold from the heat unfortunately and in turn completely ruined the gasket for the last cylinder. At first it was just a tick tick tick when cold now everytime i downshift or let off the throttle you can hear loud backfires from the motor escaping the manifold and a bit of a sucking noise under boost. I know this isnt ideal to drive with due to it sounding like a tractor but the manifold gasket and studs have been purchased and im just waiting to buy a new front pipe and decat to do all my exhaust gear at once.

So as the topic states does driving around like this cause any problems e.g bad for valves. I know it takes longer for turbo to spool up, cant hold boost for as long, sounds terrible, backfires very loudly etc but more worried about the motor as this is my daily driver. I would of thought it would ruin economy but it has probably been better as i have been rarely hitting boost. Its a rb25det btw with a stock turbo and internals. Within a week or two it will be fixed but i rely alot on my car and time is always short. ANy input will be greatly appreciated

I drove around for a month with 6 snapped studs no gasket.

Did no damage.

Just dont go trashing it.
