i' *think* the actual tip itself of the prodrive is pretty big but it looks a lot more subtle than the cannister you posted.. because the whole thing actually mounts properly under the car and looks OE

check out this youtube of a WRX with a prodrive exhaust.. btw prodrive has both round tip and oval tip. the flow is the same tho



the stock STi muffler isn't that much of an upgrade. one of my friends replaced his saabaru muffler with a STi muffler (rest of the exhaust stock) and it sounds pretty much the same as my '02 wrx.. not worth it IMHO.. not much of an upgrade.. you have to it pretty much for free to make it worth it
