FI HFC, Berk HFC, or Stillen HFC?
I live in Cali and I have a Stillen exhaust, and wanted HFC's, but am worried about when its time for smog. Should I be worried? Which one should i get and whats the difference between them.
Personally, I don't think test pipes are really worth it. HFCs already yield noticeable improvements so why go w/o cats? It hurts the environment and also causes other PITA things like staining your bumper if you have a lighter colored car.
