Weird noises
First post here guys!
Sorry if it's a noob question and if it's in the wrong section.!!!
I've had my brz for almost 5 months.
About 3500 miles
I have a perrin catback and an air filter installed
Lately from 2.5k-3k rpm I hear a sort of hissing noise
And I can feel it on the throttle (maybe because my ears confuse my sense of touch) is this normal?
Also in any gear when I apply more than 80% throttle, I have this high frequency pinging noise from the engine. It was not like this the first day I took it home.
Anyone know the issue?
Thanks for reading!
