I don't like how they gave a 'one size fits all' idea for the headers,that's half assing it. Most vendors sell a non e-gas and e-gas set of headers separately.

I was hoping to get a little more midrange and slight top end increase from these headers. These definitely gains to be made by looking at the tiny unequal length factory pipes.

this was dynoed when the car was completely stock. done in 4th gear. didn't bother to open up the engine compartment thus no rpm readings.

as you can see at higher speed(=rpm) there are many inconsistent dips on the graph this is where I expect an aftermarket headers would improve over stock headers. but interested to know what other explainations you may have for the "dips"? knocking?

Finally got these headers installed. Have to say I LIKE THEM As far as fitment goes it was quite straight forwards sits perfectly underneath the engine and looks good too (like what the car should have had coming from Porsche, compare to the strange looking factory items). Not much hassle getting them aligned with the existing system so they were well designed but also thanks to the midship horizontal engine layout. I could have done it myself but got a workshop to do it anyway since it takes half the time on a hoist.

Let me know what you think
