Don't get me wrong, I don't think you would see massive gains in power (NA) but when you have a few components that all make a "negligible" difference, those "negligible" differences can add up to being a good 7kw (for example) and we all know that when staying NA every kw counts...budget dependent.
I don't think swapping your Borla header out for a Kamak/Tomei will result in enough of a gain to actually FEEL the difference, but when combined with an overpipe, DIF and free'er flowing 63mm exhaust, it might actually add up to something.

Agree! Having an overpipe to match the rest of the exhaust system will most certainly make a positive difference, it will however be very small as the overpipe is very short. Not worth the money IMO unless it come part of a packaged deal
