Hey guys

In the morning when i start my car and leave to work i hear like a yo-yo sound coming

from somewhere in my front end.

like a cuhooo........cuhoooo.......cuhoooo....

my exhaust noises eventually drain out this sound..

and i don't know what it is

and i don't even know what to start at if i go to the dealership for warranty

i drive an 06 Manuel tc with like 25,xxx miles

my mods are sri, catback exhaust, n thats it for performance mods

So u guys have any ideas?

 

it's probably just the car warming up and you're noticing the small noises that most of us are just used to or don't even notice...does it go away after it's warmed up?

 

Well i dont know if it does cuz then my exhaust gets louder and i lose it.

 

well first listen closer.
listen to it on start up, try to listen for it while driving (i know it may be hard cuz u said you have exhaust)
and after your car is fully warmed up park it and listen for it from in the car, also pop your hood and go listen to it from the outside.
