I don't think it matters. You either use the "biscuits" or not. If you don't have the "biscuits" I think the hardware is something like $10 from Porsche.
Here's a great post on the subject:

Actually, I think they're nicknamed "donuts"... and you'll need four of them if going from a Bishoff cat to Gillet mufflers. 2 donuts to the cat, and 2 to the tips.
If you can readily find donuts at $10 each, BUY THEM!
Typically, they are anywhere from $25 to $50 ea.
I was considering swapping my ll's, but not if it's going to cost me $100 to $200, plus my labor involved. Just not worth it, IMHO. I really like my ll's!

So....not surprisingly the Stage III’s are just too loud wihen combined with the new 200 cell cats so I’m on the hunt to buy a set of Stage II mufflers or swap my III’s for your II’s. There is a catch though my ceramic black OEM wide oval tips are welded on. PM if anyone is interested.

I think these will be plug and play for either bischoff and gillet systems, meaning you will not need the exhaust seal rings aka biscuits and donuts. P/n is 928-111-246-05
The rings are only needed when you have to mate the exhaust tips to the muffler. The sellers mufflers have tips that are already welded on. GLWS.
