BDR chassis dyno/side pipe test

[native1]

Finally back from the welder and then the dyno.. I must say I am little confused by the results. The pipes sound much better, a lot deeper but not much louder. Stainless specialities made the muffs and they were very nicely done. 3 inch straight through polished stainless 4 inch O.D. Heres were I get confused, my last dyno printout showed 467rwhp however the owner of the dyno said that convertd to 454rwhp. I don't know what the heck he is talking about but I guess that means it really made 454rwhp two weeks ago not 467. Maybe some of you guys can shed some light on these different software conversions???? Anyway, the new non converted HP is 461rwhp and 449rwtq. That means the new pipes made 7hp and 15fptq more. I was hoping for more considering this project cost 1000$ The carb fuel/air mix remained the same @ 12.9. The MPH @ 6200 was 130mph. I will post all different dyno printouts that I have, Maybe some of you guys can make sense of it all. So what's with the different conversions?? I was excited at 467 now I guess its really 461 but actually more HP. I don't get it?? I think the new headers will really help out. Will be a few months for those. Anyway the sound alone makes it all worth it but my goal of 500rwhp is going to hard to obtain without a little more help.
