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
