is there a hp diffrence with tailpipes vs. turndowns

This is turning out to be a better discussion tnan I thought! Now when you guys are talking about losing low end torque, how much of an estimate do you think is being lost? I mean if I am losing a few ft/lbs of torque, thats not much to lose sleep over. If I am losing upwards of 10, then thats something I may blink at. I personally don't think a little low end torque loss with 4.10's would be all that noticeable. Then again I have been known to be wrong on a lot of my guesses. I am just trying to find out how big of a loss can be expected and if they outweigh having to tie up the pipes everytime I go to the track.
