So, i had to rebuild my turbo recently, blew the seals and the rear bearing was gone. This happened at the track. Anyways turbo is back in, works fine. Only thing im concerned with is the exhaust kinda makes a loping sound like you get with cams i guess? Its really mild but just wondering if i should be concerned. Dont know if im just paranoid bc i blew the turbo and im worried somethings wrong internally too or what.

 

video/audio clip? Any misfire codes?
