is there a hp diffrence with tailpipes vs. turndowns

I agree. I used to run turn downs for a while...when I was younger, dumber & wanted to have as loud of exhaust as possible. I reinstalled the tailpipes to help quiet it down...& gained a bunch of low end torque back. However, my 1/4 mile time didn't really change but there are so many variables when running at the track that that small amount of torque I gained back may not have shown up on my time slips due to track conditions, weather, inconsistency in my driving, etc.
