What do they change?
Hey i was wondering why you need to send your computer off or have it dyno tuned when you get headers and ory put on your car. What do they change when you add these parts. I know they delete the rear o2s but what else is NECESSARY. Thanks.

The bottom line here is if you want to get the most out putting them on, your gonna need the tune. No, it isn't necessary but what is the point in getting them if you aren't going to use them to their full potential.
