ok..i had a problem where i was hearing a squeeking sound when blipping the gas to 4k and letting it drop. i thought i was coming from the engine. brought it to acura, they couldnt find anything wrong. yesterday, dropping my bro off at the airport, he hears it too and tells me its coming from the exhaust. so i have it blip the gas a few times and it is coming from theres. do you guys have any ideas what could be wrong?
