The MY15 991 GT3-CUP uses the standard 997/991 GT3 rear muffler #997.111.027.92. The "pre" mufflers are a little different, they're refillable. The other option they run are just two S pipes coming directly off the cats.

You can effectively duplicate the Cup setup but going with the M&M side muffler delete kit that uses their own center muffler and side muffler delete pipes. Talk to the folks at FVD.
