    Q: Does this part have to be welded into place?

      A:

      Happy to answer your question Jeff! You have both options actually. This part can be welded or clamped. If welded we suggest also using the muffler strap hanger Part No 36234. If you decide to use clamps the diameter of the inlet and outlet is 2 inches so you can use Part No517214, 2-1/4 inch exhaust clamp.
