Exhaust on a 991.2 cup
I have a stock 2018 991.2 cup from Europe that I just got and it came with a center muffler.
Is there any performance increase by running the open (super cup) exhaust in lieu of running the center muffler?

Center muffler actually produces more power than the supercup pipes.

I believe all us cars were delivered w straight pipes. IMSA Platinum / GTC7 spec will require these if you plan on joining us.. Livery looks damn good btw I recognized it at road atl but didn't know that was you. Best of luck with it!

I have been told the opposite - from Cup's that have been on the dyno the rear center muffler/side bypass pipes produce the highest output. Supercup drops the power slightly (assuming drop in back pressure, but couldnt confirm this as have been told by a few shops that work with these regularly).
