That depends on how you count them. The factory says 2, a front and rear, however the front is actually the Y pipe that mounts to the engine and it has one convertor on each side that are connected at the rear flange where they bolt to the rear convertor, which is also 2 separate units joined with a short pipe. The attached is what I mean.
