The engine isn't knocking or pinging, it just seems loud. Not over-exerting, although when going 75 mph on the freeway it's at 3500 rpm, but as the car is going at higher speeds it just gets loud. So loud you can almost not hear the change in engine sound when shifting gears. Is it the exhaust manifold or manifold gasket (nothing has been done to the exhaust system yet). I am the original owner, and the car has been serviced regularly, and always at the dealer. I do not smell exhaust in the car, there's no rattle, no clicking, just loud, like an engine sound overlay over the normal engine sound, if that makes sense.
