Gaps where pipe meets stove collar

[Jesepi]

Hello all,
Where my Imperial single wall stove pipe slides into the collar on top my stove
there are a couple gaps where the pipe doesnt fit tightly. Its due to the fact that I had to put the pipe together and it got a bit misshapened.
Will that be ok or will it be a problem as far as smoke or flame leaking out the gaps ?

Not a problem with flames or smoke leaking but may be an issue with air leaking in

How would air leaking in affect the draft? Would it decrease the air flow, or vacuum, heading up the pipe?
