Hey chilliwilli, what exactly you want to know? If you bring your car to the agency they will not know that you have headers.

We have cars running our RS720 setup almost 80000km now without any sideeffects. Ofc it depends on the driver how you care about your car..

If you want more to know hit me a email at [email protected]. I will also post some more pics, videos and dyno sheets about our tune!

Cheers
Thomas
