No, it's a resonator (or Submuffler in Toyota terms).
I'll work on a DIY for it before mid-August. Yes, you can cut out the resonator and replace it with a straight pipe. But the muffler shop is going to have to fabricate two exhaust support rods because the originals are welded to the submuffler. See the photo below.
I'll have to pull the drawing, but I believe the tube diameter of the pipe is 54mm. ( 2 1/8 ) This is a tube diamter that muffler shops almost never carry. (No bend tools for it.) So use 2 1/4" and reduce the ends to 55mm ID.
