1/4 mile gains w/ headers alone

[Russ]

Wondering if anyone can report what 1/4 mile time improvements result from headers alone.

Hearder/Exhaust netted 0.4 sec for ET time and 5mph for trap speed for me. Very unsciencetific test since it was at a different rack on different day but you do see inprovement. Just header itself, I'm not sure what the number would be.

Smaller than the normal variation in most people's 1/4 mile runs...
