Weird Growling sound when high rpm shifting
 

Can anyone help me whats wrong with my car, it makes this weird growling sound coming from the front right of the car, possibly from the intake when shifting at high rpm. It happens all the time, both when car is cold and warm. I've also noticed power loss. and quiter but more drone exhaust sound, when the car is warm.

im dead certain about these sounds and power loss, not just in my head. My brother feels the same.

Car is 2013 AT Ft86 with
HKS Aluminium Inlet Tube + Drop-in filter
Dastek Unichip Piggyback
Catless full exhaust

Probably vacuum leak or exhaust leak. Need data log, best tool for troubleshooting.
