I have a 97 XK8 with Mina Exhaust and would like to replace the Center Muffler too. Does anyone know the part# or who to contact.

 

I highly recommend going with an X-pipe in the middle section. Sounds better in my opinion, and is cheaper (and at least 50lbs lighter!).

If you insist on a center muffler, check out the x pipe dimensions diagram in my signature link, and purchase a center muffler with that correct diameter inlets and spacing between dual in/dual out pipes. Any competent muffler shop can then install it for you.

 

Hmm.... Sorry, I don't have the model number and I can't find the exact muffler on their site.

Call Borla and ask for the Dual In/Dual Out with the built-in X-Pipe.

That's the one I have installed in my XKR.

EDIT:

I found it searching my email.
