They would sound like any other downpipe, depending on what you have after the down pipe when it comes to mids and exhaust. Are you going for a distinct sound??? Going catless is going ot net you better HP upgrade but to extract that HP you have to have a tune with it.

If you are looking for a different sound, exhaust and mids are another option instead of Downpipes.
