I don't think running a header without a tune causes damage...lots of people run the borla with a spacer on one of the o2 sensors. However, you won't see the gains that you could get with a tune
But the oft(open flash tablet) is pretty cheap, and you'll get the most gains for oft+header... |

Bump from the dead, but my J2 front pipe certainly made a difference in throttle response, not sure about the top end if theres a difference but throttle response certainly improved.

Out of curiosity, is a resonated front pipe even worth getting when you already have a header ? I'm skeptical of how much of an improvement a front pipe will make when you already have a header.

Looking at your mod list, I doubt you'd notice a difference in performance. You've already done the big stuff.

You should try a straight pipe with some unrestricted header! Also, change the drop in to a whole new intake since the stock have a lot of turbulence. In other words, the intake slows down the air.
Or TurboCharge the car and go with rich ethanol fuel.
