exhaust leak???




what do you guys think?
any side effect of this??
also, when I press gas in neutral, I hear little shudder vibrating right after
I wonder if this cause of the leak?
I had this exhaust for about 8-9 month, I just noticed it today.
exhaust is PE.

ok
after the car had been warmed up
everything is normal
no leak and no vibrating sound, no more moisture
the car has been sitting in the garage more than 2 month but it was started once a week at least. I was kinda worried lol

Look on the ground where you park overnight. usually leaves a small black carbon spot. Or on the exhaust pipe section effected.

Garage List
My guess is those clamp bolts are not tight enough. The BMW recommended torque is 70Nm!
