The brackets that hold the exhaust pipe and tail pipe to the frame. The originals are solid metal brackets that don't allow for any movement of the pipes with heat expansion (or maybe even frame flex) and can transfer the stress to the manifold, cracking it. I haven't hearrd of this being a problem on the 230 as much as the 251.
