Loud noise when press on the gas

I have a 1997 Honda Civic LX 4 Door. When I press on the gas, the engine makes a loud noise. It sounds like something is wrong with the exhaust, but I just had the muffler replaced a year ago. The sound seems to go away at 40-45mph, but then comes back. The noise is not contstant, but pretty close. I'm thinking that it might be the exhaust manifold, but not sure. If it is, how difficult is it to replace the exhaust manifold?

See if te noise is there when stationary. if so hold the revs around 1500 to 2000 rpm if it rattles around that, then it is the heat sheild on the down pipe section thats broken free.

1997 honda accord loud buzz near engine when accelerator pressed?

Sounds like either: 1) A exhaust heatshield is loose. They're simply thin metal guards around your muffler/CATS. If you find one loose, remove it or have it welded back on. 2) Broken motor mount. This is serious and requires pulling the engine from the car. If a motor mount is broken, the engine wont sit right and cause multiple vibrations. Hope this helped!
