Intake: Stillen Gen3...hands down.
HFC: not much difference between brands as the catalytic converter is supplied by the same source. ERZ, Invidia, Berks...go by best price.
Exhaust: depends on quiet vs. loud, looks, quality of build, price. 2 of 3 of my vehicles have Invidia exhausts. The 3rd one is brand new and will get one too in a couple weeks. Invidia has yet to disappoint me.
