ER Downpipe sound when cold

Greetings!

I just installed my downpipe a week ago. All were done succesfully removing the exhaust and following instructions. I noticed that when the car is cold, it sounds like it has some air leakage but after 45 seconds is gone.
I checked everything and the vclamp was a little loose, so i got it done.
Still has some sound when cold.

Is that normal sound?
I will post the sound tommorow moorning.
Thanks to all.

thank you for the video clip, so catless DP with jb4 with my MPE exhaust will take care of any CEL and also give a nice good sound? No point for catted then

Correct. As long as emissions is not an issue for you.

emailed Fred Su of ER and he told me to check the white gasket between the downpipe and the turbine (the vclamp one). Will need to replace it so the sound will be less when cold.

I replaced mine after a lot of back and forth with Fred. It did not solve the issue. The sound is still there. I even took it a step further by using fiber cloth as a typical exhaust gasket would be but still have the leak sound, no better or worse. I had given up some time ago.
