Anyways, to get back on topic, I am contemplating getting a true dual for my Vortech. I am a little worried about losing low end torque, because these engines already lack good low end power. How much whp/tq gain could I expect if I updrade to a TD exhaust? Btw, I have resonated TP's+3" Y-Pipe+Exhaust...I am also hitting 8.5 psi on 3.33 pulley.
