My 2000 Honda passport is making noise

It sounds like a one of those loud motor cars.

Mine does the same thing but it sounds like it's coming from the bottom of the suv

same problem

SO i have a 02 civic ex with a d17a2 in it, car well my grammas she lived in a seniors home and walked everywhere in town used it maybe once a month, was taken for full maintenance twice a year, i started driving it and might not of notice it at first put when i press the gas it makes a slightly hissing noise like a manifold gasket gone, it stops when i take off the gas, it does not struggle in power i can hit 7000rpm no problem and pick up good. fluids all good, its auto and sounds like its coming from the left, not the cv or any of that and it does not get louder or quiter stays the same but only under power
