Loud roaring noise when accelerates

Question type: Maintenance & Repair

I have a 2005 Pontiac g6 that started making really
loud roaring noises yesterday when i accelerate or
turn on the car. No engine light is on, what could it
be and is it expensive to fix? I thought it could be
the muffler but I honestly don't know anything
about cars.

where is the noise coming from? sounds like an exhaust leak somewhere.


there may be an air pump that feeds the exhaust with a hose loose or worn , or EGR valve , pop the hood and rev the engine , if you know nothing about cars then what do you expect to do ?

I'm just trying to see if y'all think it would be am expensive issues or something thay can be fixed at home, the noise is coming from the engine I'm 99% sure


There's no telling what it is or what tools you'll need , none of us were born with mechanic experience so have at it if you want


The exhaust manifold bolts onto the engine. Still say exhaust leak.
