just wondering if having headers with 18'' extensions is hurting my bottom end im all stock motor i like this because of the weight savings but with the stock cam and intake im not sure if this is beneficial car is mainly on the strip and thinking maybe a little back pressure could help make low end torque to bring my 60ft time down

I have seen where people dynoed there motors with no mufflers vs open headers and they lose Hp on here. I would at least do a y pipe with a bullet muffeler or do two bullets mufflers 3 1/2 inch. off the headers.
