turn-down pipes TORQUE IS GONE!!!

[StreetStang37]

I have cutouts before my mufflers and with them open, it feels as if there is more lowend torque. I have run several times with my Gtech and would always trap mid-low 103's with them capped and high 104's with them open. I know a gtech has high trap speeds yadda yadda, the argument isn't about that. I find myself driving in lower rpms with them open than closed, I feel there is more power with them, so I doubt your losing any power at all having turndowns vs. piping to the rear end. I've read that you make your most power with 12 inch piping after THE HEADERS, not mufflers. Does anyone have any dyno information to verify any of our arguments. What I have written is my opinion and experience but I could be wrong and I can accept that if I am.
