True story lol.
100-200 is not a primary concern for my GT4, if it were I would have bought something like a z06. No logical person bought this car for the numbers it produces, it was bought for the rewarding involvement of driving it. The idea of a little more midrange, even if there isn't much improvement in peak numbers is appealing to me. I plan to get some of these mods in the future just to enhance (not change) the experience. I do not want a 911 so I will not put the money towards a GT3. I want my cayman, I just want it to exaggerate its character a bit.
I found that fabspeed sport headers and TB transformed the car on the road. It's got nicer torque characteristics when pulling from lower revs, and now it keeps climbing instead of flattening out noticeably at top. Not to mention the sound difference. It Was completely worth it for me from a $/enjoyment perspective.
My tuner says that the real deal is the fabspeed pro tune... the ipd+tb combo helps a bit but the gains are from the Cobb-Fabspeed tune....
This is a comparison between my old " only sport headers" run and one run that we made today with all the hardware installed but with Cobb stock/base map (0 map)...and not with the custom map

Each to his own, I personally do not believe that it´s just placebo or confirmation bias.
I made two close friends drive the car before and after without giving too much information, just like
take a spin and tell me what it feels like. Both were stunned and told me it felt like a different animal.
Maybe dyno numbers and seconds are not the whole story when it comes down to "feel", there´s a lot in the way power is delivered over the rpm range. I guess the wide gap between the two curves along the midrange is what makes it actually feel so good on the road.
That a-worxx GT4 is btw. a different story. As I read in another article, they just modified the stock headers by welding HJS 200 cell cats in them. Makes no sense to me, having seen stock vs. CG sport headers on my garage floor. There´s also no plenum or tb, just the bmc filters.

A lot goes into the development of a more efficient header design. I can tell you one thing that is NOT conducive to making performance...having an empty cat chamber for turbulence in the exhaust flow. Not surprised to hear Rick saw no gains with the "gutted" version of the factory headers.

I had an IPD and TB installed a couple of weeks ago and have registered for a Supersprint event at Eastern Creek in Sydney on the 4 Feb. I will be looking for increased main straight speed and will update after the event. I have data logs for the unmodified car. I also had rear toe links installed and a -ve 3 F and -ve 2.75 R set, so speed onto the straight will be slightly higher (hopefully) but still using MPS cups. I will let y'all know the outcome.
