Open Headers = New Personal Best
I've always wanted to try open headers at the track but driving it there then dropping the cat back and y pipe at the track then putting it back to drive home was not worth it. So, I dropped the cat back at home loaded it on the trailer and hit the track. First run with y-pipe 10.87 DA was only 90 best one I've ever seen. I thought that sucks what a waist of time. So I made another run this time 10.85, still disappointed. Now I took the y-pipe off and ran a 10.84 a new best but still come on. Decided to hit it one more time and boom 10.78 @ 124 DA was 500ish. Now that's better. Since the car's getting faster all day I said one more time, 10.81 @124 DA climbed to 1200ish by this time. Best with full exhaust was 10.85 @123 vs. open headers 10.78 @124.

Very nice! Pretty damn consistent. Did you modify the tune at all to run with open headers? They say leaner is meaner lol
