Just curious about when it is really WORTH it to upgrade to aftermarket headers.
I am currently running around 127mph in the 1/4 and wonder if I will pick up any ET going to a set of ATR headers.
how fast have people gone on stock headers?
any back to back testing?
I guess the same questions apply to my stock unported throttlebody.... when is it worth it for me to upgrade that as well?
