Headers VS Manifolds
This will be a very subjective thread. Interesting too.
Really comes down to what you need from your car to get the thrill. Im at a 13.2, 1/4 through manifolds, in full street trim and on stock tires. I have no doubt that I could touch the 12s if i play with it and learn to launch better on the E70-14s.
The car does everything I need it to do for giving me that rush of excitement when I'm out for a drive.
Like others have said… If you are strictly looking to maximize performance, headers should be part of your plan.
