This can has a bit more bass than the standard one.
MTC asked for some pics & sound files so they are here;

Quality isn't that great as it was with a pocket camera and i also didn't rev too hard with either can - doh!
They also sell de-cat pipes for my bike for £200 which is by far the cheapest anywhere. They are an honest bunch as well, they told me not to buy the de-cat
unless I kept the original can on. They ( and others) have said it is much, much too loud.
