GMMG exhaust
I agree with RevGTO about them probably not being made but look up "madhammer exhaust" - can't remember the website. He was the guy that made the GMMG exhausts and still makes them and other parts. I ordered a part a year or two ago from him and excellent work still.
I'm almost certain you can get center exit "tips" that will bolt right on to a Madhammer/GMMG exhaust. I think a lot of the Berger cars actually have a GMMG center exit setup.
If not, you can always cut yours off and mount them on a GMMG exhaust.
