Louder but not much louder if the rest of the exhaust is stock.
They are made by Borla and the two exhausts that is comparable would be the Borla Touring and the Borla S. I'm not sure if there are many good videos showing the difference between the GMPP's but there are a few showing the difference between Borla's so that would give you something to look for as well to give you an idea.
