Just bought a nice 300SDL which recently had a complete Trap Oxidizer and Turbocharger replacement. Trouble is brewing, however, as the accordian piece between the head and trap is now cracked, allowing exhaust to billow into the engine bay. The local dealership has quoted some $500.00 cost to replace the pipe, as the head must come off.

Can anyone inform me as to an alternative method to re-seal or replace this piece? I was thinking muffler tape with some slack around the piping or dropping some liquid metal into the crack. Trouble there is pliability, adhesion, and temperature/expansion mismatching.

TIA,
