Some have different ends where it meets up to the rest of the exhaust. Hypermax has a 3.5" lower section and just a slip joint at the bottom so you have to cut the flang off the cat to install it. But it makes for a nicer install if going to a full 4" system. They are also one of the cheapest. Most all of the rest of them have the flange that bolts to the cat. Some have a bung welded in them for a pyro probe. Don't buy one based on that. You don't want the probe there anyway. You want it in the exhaust manifold.
