my question is how much time can you knock of runing open header. I was runing open header today and wanted to know what my time probally would have n\been if i had the whole exhaust. It wasn't intentional. I ran it and on the 3rd run i broke the weld from my flex pipe and the mide pipe. My first run i missed 2nd and ran a 16.08. My 2nd run i ran 15.630.my 3rd run i boke the flex pipe section on it and ran 15.502. I figured **** it and kept runing it. but i adjusted my tire preassure and got better at launching and brought my 60 ft times down to 2.1 and 2.2's. My best run was 15.251 with a 2.195 60ft. I don't think it was the open header that knocked of 3 tenths off my time. or atleast i hope it wasn't. i hope it would be that i was just getting better launches.

clif notes

broke flex pipe and mid pipe at on 3rd run at 15.502

by end of night with open header ran 15.251

was this only cause open header or would open header not really help that much?

depneds on the car with your setup it look likes it knock a tenth

 

Knocked off 3 tenths, when I ran open header versus through the exhaust.
