Kevin, yes, the tips are the same with Bischoff and Gillet

The outlet on the muffler is the difference
Either tip will fit your setup

check for contact between the tip flange-shield-thingy and the cat shield or bumper cover

Take tip in hand - drop on floor ... if there is a tab/heat shield/etc loose, you can tell by the sound.

If so, tap it with a hammer/cold chisel/screw driver .... to find where it vibrates ...

Have a chum MIG a spot of weld of said point ...

If you have neither chums, nor favours to collect, a deft strike with a ball pein hammer may sufficiently reshape the metal to take the resonance vibration frequency beyond your range of hearing ...

Reinstall tip & drive on: no, it's not perfect - but it wasn't concours to start with ...

On to next problem - there is always another waiting ...
