When i disconnected the valves resulted too loud and too much drones between 2800 3500rpm
very annoying when cruising
tried with stock side mufflers stock center valves disconnected
and side mufflers delete with valves disconnected to stock center but no luck
curious if 100 cells headers plus a side muffler delete with valves plus Akra center muffler (slip on) could be the solution to have when valved are closed that extra bit missing between 0 and 4k rpm without going too loud
now i have the modded headers (200cells) and soul side valved delete plus the stock center mufflers
valves disconnected as said equals drones and booming
strsight side link pipes less drones than valves disconnected but even more loud and booming
going to buy a used akra center slip on if any wirh low miles (low carbon...) available

Center bypass and valves open all the time. The perfect set-up for me.
I do not track so really do not need side delete. Have every other light weight option- PCCBs, LWBs, Lithum Battery

Stock system with valves disconnected does not drone and is not loud or much louder than stock.
I have Soul Side Muffler Deletes.With valves connected it’s still,super quiet at low rpm and opens up nice.y abvove 3500 or so rpm. However still too quiet for me at low rpm
I disconnected the valves and it’s much better and still no real drone going on at low rpm. Much more fun and exciting and not really loud at all at low up to 3500 rpms.

(I thought the character of the stock system was quite ok with disconnected valves, linear and enough "open". If were it not for the drone, I would have kept it that way. My 997S did not have the drone with PSE valves disconnected and it sounded marvellous...)
