Altho this may not benefit since there is no heat shield on these headers which means the intake will take in more hot air and the intake pipe that leads to the SC unit will be baked, but this can be easily solved if someone wraps it.

I actually have a set of art pipes (v2 with the ceramic coating) that i will be swapping with my berks HFC, to test out both fitment, and change in output. I'm currently in the process of making some gaskets and will have to tune the car slightly when everything is install. Hopefully i will have full results by the week of 20th-25th.
