PS my friend wants to know do you have these headers for 991 GTS or similar headers for 991 GTS?

Thats what I thought but after many attempts, I think its not goint to happen. My best was 11.089 @ 124.7 and 11.099 @ 126.9 But the second one was on a colder day with a bad 60 foot.
A tune would definitely help the car break into the 10s

The engine may physically be simiilar but the headers will not bolt on. I will be building those here this year in the future. The flange and bolt pattern is different, but the header design is different as well. That is about 3-4 projects down the line before we get to it.

Another thought that might help is a DSC box to program the dampers for a better launch...

The 991 C2S and GTS share the same base engine so they physically would fit. I will just have to do the needed testing on the dyno before being able to fully produce them. The GTS has the x51 power kit so I would want to do separate testing to see if that setup wants a specific header design compared to what the regular 3.8 would want.

I know that the 991 RS is not designed for straight-line speed but it would be interesting to see what the 991RS would be able to run with the dundon headers in place for the 1/4 mile. Would the extra HP of the 4.0 motor negate the more aggressive down forcing of the RS?
Motor Trend tested a stock RS in the quarter-mile at 11.1 at 125 MPH
