Alright guys, here are some vids.

As you can see, I still have plenty of low end, tire shredding power.
No brake boosting and I laid quite a trail on the third video.
Sounds a little raspy from outside, wasn't expecting that. I think I'm probably giving the Dynomax Super Turbo's (3 pass chambers) a little bit of a workout.
At this point, I'm thinking I should upgrade the mufflers and up the piping to 2.5 inch. Let me know what you guys think.

PS I've been having trouble with youtube so let me know if the vids don't work.

Ok, went to the track tonight, 1/8 mile.
For reference, I've been to three different tracks. Mooresville, NC (1/8) ; Rockingham, NC (1/4) ; and Darlington, SC (1/4). My best run (Rockingham) before the headers was:
RT .027
60 1.967
330 5.687
1/8 8.686
1/8 mph 82.15
1000 11.306
1/4 13.498
mph 102.14
Before tonight, the last track I was at was Darlington. I was not running very good there at all. As far as 1/8 mile stats go I was in the 8.7's to 8.9's and only had one run that the 1/8 mph was over 82 mph.
My best time at Mooresville, before tonight, was 8.795 at 82 something mph.
All of the times listed above were with my current setup minus the headers. I have not made any changes since the above runs and tonight except for the headers.
Ambient temps tonight were very close to 90 degrees, about the same as the last few times I've been to any of the tracks, including the above listed runs.
TO THE POINT.
My best run tonight at Mooresville:
RT .127
60ft 1.950
330 5.632
ET 8.569
MPH 84.035
This time is .226 seconds faster than I have ever run at this track and .117 seconds faster than my prev best 1/8 mile time ever, which was at Rockingham. This is also almost a full 2 mph faster than my best time at Rockingham. If you averaged all my 1/8 mile trap speeds, I am now 2 to 2.5 mph faster. This is quite significant. This should put me around AT LEAST a 13.3 in the quarter. I'd be willing to bet I'd be closer to a 13.2. The standard formula to calculate 1/4 time based on 1/8 time is 1/8 time multiplied by 1.55. On average based on my past 1/4 runs, my car does around 1.54 to 1.545.
I am very happy. I was only hoping for a flat 8.6!
Some other notes.
I am actually shifting to third before I get to the 1/8 mile mark.
Between the three tracks that I've been to, I've probably done 50+ runs. Out of those 50+ runs I've had only 4-5 runs with sub 2 second 60ft times. I had 5 runs tonight with sub 2 second 60fts. 1 or 2 of these was with wheel spin!
My traction problems are much worse now. Before the headers, I was able to stomp the gas (no brake boosting at all) and take off without any spin. Tonight, I had to feather the throttle to wide open or I'd spin.
I am very happy. I also think that with a few more back to back runs, I'd go faster.

did you have to extend the 02 sensor wires? Living in cali isn't exactly great so I'm throwing on some high flow cats after these headers. Looking at the pics, it seems like the 02 sensors after the cat is going to need extensions... can you confirm? were the 02 sensors pre cat long enough to fit into the headers?

Grab a cheap used set of 275/40/17 Mickey Thompson drag radials and see what it does. Auto cars don't hit the tires nearly as hard as a manual car so you could probably get away with it for a while.
