Just got off the phone with Marcy Motorsports in Cali, talking to them about their new 4-2-4-1 header---delayed until the SEMA show in Nov.--and after a lengthy discussion he came to the conclusion that I would be wasting my $ spending $450 US on the header and flex pipe with the SC application.
He said that we need some backpressure for the SC, and the shorty would provide this perfectly for us, as he has been testing both naturally aspirated and forced induction set ups for the new header, along with the FC,FS and JBA header, and said that I would gain a modest 3-5 hp, but lose torque.
He has suggested a random tech cat and just changing the flex over to a 2.5"

I know Marc And Kevin that you have piped up in the past about getting the race header, but this seems to go against what you guys have been talking about. Not to say your not right for a Focus that doesn't have forced induction, he even said that's where they are seeing huge gains of up to 15 hp, but with the JRSC, I am now rethinking the decision.

Comments???Anyone???
