Just got all the data together from our Dynapack Dyno on a long awaited RS we were privileged to get to work on.
As most of you know...
Constructed from 321SS tuned length stepped headers and flapped side connector, the exhaust combination offers a 40whp increase for GT3 owners and 40whp for GT3RS owners with no ecu flash required. By understanding exhaust flow and resonance tuning, Dundon Motorsports developed this combination. The use of the the OEM center muffler and flaps allow for drone free, quiet cruising and a glorious porsche roar when on the throttle! This setup is bolt on and can be selected with or without the exhaust flaps.

And for those that didn't see it, check out our other thread, the next graph will make more sense...
50whp gains?, nope, just shows that the RS is sensitive and baseline runs have to be thoroughly vetted before you take them as true baselines... 50whp?? , nope, just shows that the RS is sensitive and baseline runs have to be thoroughly vetted before you take them as true baselines...
And last one for fun, 991 GT3RS vs 991 GT3 both with Race Headers
