Maybe a silly question but hfc or test pipes?

I have the injen true dual exhaust been having it for years in my 04 coupe but never thought about hfc or test pipes. I haven't done headers but wondering which would be better and give me alil more power. Need to tune it also. Any help

Fast Intention HFCs, they sound better than ART pipes and are legal in most states...just not mine!
