This is a DC5 R exhaust. It is has a larger diameter piping then the RSX Type S does. The exhaust is also more free flowing and still very quiet. The tip is also bigger then stock. Mandrel bent from the factory. When purchasing this item note that it includes the B - pipe and axle back. This makes it a complete catback. Also just found out that the muffler has a special valve. When it is in high RPMs the valve opens and when it is in low rpm it closes.
Fits: 02 - 06 RSX. Type S only.
Here's an inner picture of this special muffler can from Honda.
