07 Civic Reflash and CAI
Posted: Fri Feb 25, 2011 2:35 pm
Hi,
I am new to this and have searched but have not found answers. I would like to add the reflash to a 2001 Civic Si. To do so I understand that I need at least an intake, header or a combination of both. I would like to just replace the intake, but was curious:
1) How much difference in torque and HP will there be between stock, reflash + CAI, and reflash + CAI + Header.
I am not so much looking at the numbers, but rather feel and performance but i assume the numbers will be the best way to tell.
2) I beleive I have read that a Cold air intake is much better to pair with the reflash than a short ram. Is that correct?
3) If 2) is true, is there a specific brand that you recommend? AEM or Injen seem to be the most popular based on my research?
Lastly, if adding a header makes a BIG difference in addition to the CAI and reflash, again what models are recommended? I would like to stay emmissionis legal if at all possible, so does that mean either the CT Engineering shorty or the Vibrant with a cat? If so, which one works best?
Lastly, I seem to be concluding that an exhaust is the least beneficial and will not make any material difference. Is that correct? If it was material and not just a few HP and ft pounds, then I would like it fairly quiet...and for that I think there is one Greddy SE or similar? But...is that any better than stock for performance?
Sorry for all the questions and I appreciate any and all advice.
