See attached dyno curves for:
1. Race Package (catless race headers, side muffler bypasses, center rear muffler bypass)
2. Sport Package (headers with 200 cell sport cats, side muffler bypasses, two rear Mini Maxflo mufflers)
3. Stock OEM system
These curves were supplied with my GT3 when taking delivery of a system similar to the race package, with only difference being use of the Mini Maxflo mufflers on my GT3. I later had the OEM rear muffler reinstalled to get rid of the low rpm drone I felt excessive for my tastes. My final system (catless race headers, side bypasses with valves, and OEM rear muffler) had just the right tone for my taste. I also feel the throttle response of this final system is significantly better than the complete stock OEM system.

fxz,
Fabspeed provided the dyno curves as part of the arrangement of using my silver 2014 991.1 GT3 as their initial development car for their exhaust components😊.
I later purchased a 2015 991.1 GT3, which I sold January, 2018. A 2nd set of components were bought for this 2015 GT3, which I took off the car at sale after approx 5000mi use ... the race headers and side muffler bypass pipes with valves will be sold, if you have interest. Will list soon in Rennlist Classifieds.

Fxz,
Yes, precisely. After spending time with Fabspeed in 2014-2015 trying four different configs of the exhaust system on my 2014 991.1 GT3, I am of the opinion that catless headers + side muffler bypass pipes with valves + OEM center muffler was best system. This config retained the performance of the system and avoided the troublesome drone I experienced with the Mini MaxFlo center muffler or complete
center muffler bypass. Several techs at Fabspeed agreed with me😊.
