Default Open headers....Low end torque?

I opened up my headers tonight to get ready to go to the track on saturday. Will this hurt my low end torque? It feels slower from like 0-20mph, but that may be just because it's so loud and seems like it should be faster. What you guys think?

i'm confused on this too. if yur exaust is too open you lose low end torque. however if you use a cut-out (which is by far got to be the free-est flowing "exaust" possible) you gain HP and torque. how's that work?

I believe you will gain HP and TQ with open exhaust but the gains will be at the upper end of the RPMs (great at the strip-crappy on the street). Low end TQ will suffer with open exhaust. You can't have it all <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

I got long tubes and i'm running true open headers. I guess you could say open cats.
