Hmmmmm, I might be willing to do a before and after dyno with the MSDS headers versus your headers on a 3L engine. I have to be honest, the MSDS headers I feel are really choking my engine, maybe these headers would be a great alternative, maybe they will flow even better?? You can contact me if you want, I don't think I will ever be back on NECO again, except for later today to say my goodbye's.
