Hey guys. I am running the Nismo cat-back with Crawford HFC's and DC headers for my exhaust system. Now I am happy with this setup but like most of you I am longing for more power. So my questions is this.. if I add the JIC Y-pipe to the Nismo exhaust would it provide any gains. I know their pipe is really free-flowing. Anyone of you with this setup or close to it? I know the Nismo Y-pipe makes like 6whp... how much would the JIC add if any>? Thanx guys.
