GT3 side muffler delete, GT3RS max delete?

GT3
What is the popular way to go for side muffler delete on the GT3, weight and heat reduction?
Something new?

GT3RS
How much can be deleted from the RS without losing warranty (cats?) or performance?
I maybe a bit early on this one (my car is December build), but maybe the first receivers of the RS are playing with setups?

Thanks, thought it was pretty much all the same back there..
Been focusing on that DRS thingy I guess.

So only 2 cats and one final center muffler,not much weight saving possible?

Basically. Call it cat/OPF filters (more just cat for NA) plus the center.

lots of weight savings possible. We have a cat back that keeps valves. In general when keeping the OPF’s we recommend to run the mini crack pipe to get the best sound and most weight savings.
