loud sound from engine bay

[DoginBlack]

at low RPM, there is "te te te" sound, it sound like exhaust leaking.
at High RPM above 3.5k, there is very very loud sharp sound, it sound like rubbing. The sound can be always there even I had drive more then 40min trip when above 3.5k RPM ( below 5k RPM).


HOWEVER it can be temporary stop this problem if i ram my RPM more then 5000RPM for 4 sec, then ram again for 3x. The problem of " te te te" sound and sharp noise was gone. WOW, amazing ? what wrong?
