Ok, here is my question.

Toda header we know makes more power than a JDM 4-1
BUT . . . How much more would you guess a Toda header woudl make then a JDM 4-1 if one were to keep the stock exhaust?

The tests we have seen are with an SMS cat back which is nice but I am old and want my R with it's ATS Final Drive to not get any less highway worthy.

I made very little power with my POWER FC and have considered selling the PFC, buying a toda header, selling my JDM, buying a fields unit for VTEC and fuel (VAFC does not seem to work on my car; thottle reading issue just with all VAFCs) and calling it done for a while. Woudl consider Toda A's and an SMS cat back in the future (3+ years) when I pay it off and have something else to drive if needed.

Thoughts?

BTW, plan for now is to try and have the Power FC tuned again. We were a little unprepared for the last session and I want to gibe it a fair shot.
