Fabspeed has just about finalized development on the long tube race headers for the GT4 and the gains are Mr Olympia level...when the order queue opens...so should your wallet... 😆

Decent gains for headers only.

Over all numbers are disappointing, IMO.
I know this has nothing to do with Fabspeed. You're showing the graph with gains, which is most important.

If its the case that the measurements are wheel hp then its what you would expect with an NA engine with exhaust and headers. So it would make it around 445hp at the flywheel which is pretty good for a 4l NA engine. Not the massive gains to be had as per the tuned turbo engines, but gains nonetheless and I'm sure it will have a nice ring to it.

These modular headers are the perfect solution for any street driven 4.0 liter Cayman or Boxster. Our modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass “straight pipes” for track use. Rennkraft, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.

Is this on stock ecu, have these headers been dyno'd with tune lets say from M Engineering or others on the 4.0?

Yes! Fully stock other than our Headers. We have not dyno'd them in-house with a tune.
