2006 RSX Type-S
Probably used my patented method of one header in the normal spot, and then the other one bolted to the intake side of the motor. The collector sticks out the grill, and you put a cone filter on it. Boom! Cold air induction! Limits rainy day drivability though...You're going to have to let us know as there’s no way to determine that. All that can be said for sure is that your time will improve. A tune will always be better than a basemap, but you can run either one.
How'd you manage to bolt on more than one header?
