Made it back out to the track last night to test out the exhaust. Air started out @ 3300, man it was nasty.
Car was ran a 12.36, 12.31, and finished up with a 12.27. This was the exact same track as last time with the only change being the stainless works exhaust.
Here is my slip. All 3 runs were better than my previous best.
Heres a vid of all 3 runs together.

On my 12.365 Run from last time, DA was 2278 by dragtimes.com, so we'll use that as a baseline just for consistency, since they pull weather stats from the same place.

Last night, DA on my 12.275 run was 2588 ft. It was hot nasty lol. The 12.275 Corrects to [email protected] mph.
On Lamottas dyno with another car, the headers on a tuned car picked up 23 rwhp. So. Considering I picked up a tenth in worse air (corrected to a tenth in a half at sea level) I'd say those #'s are spot on.
I think the drag times calculator is pretty accurate, when i put my 12.31 run in, it corrects to the exact same e.t. base on the weather at that run.
Here are the 2 slips side by side. Left is before exhaust, right is after.
So, I know headers are a little pricey, but there are gains above the "maxed out" factory headers to be had.
I gotta think on blown and nitrous applications the gains will shine even more. This is a car with a tune, gears and tires. Still breathing through the facory paper filter.
