The big question is do the torque cones actually have any effect on the reversion pulse or not.
It is one thing to run them with and without and guess as to their worth. It would seem the easy way to know if to throw them on the dyno and look for proof.
No one has dyno'd these?

The million dollar question right there. So has anyone done testing? It seems to me a no brainer that these exhaust companies would have done all the testing, dyno work.

Pnw, I don't disagree with you at all. I'm just stating what's been written in a lot of places regarding Big Twin exhaust pulse waves and exhaust scavenging, not necessarily written by those selling snake oil gadgets. Also, I agree that I had always heard about reversion as relating to intake from my car building days. In fact, I can see that on my gf's Sportster with open pipes and the air cleaner off. The wave blows fuel mixture about three inches outside the carb before getting sucked back in when rolling on the throttle.

When I bought my 2005 SE Fat Boy, 5 years ago from the original owner, it had Samson 1st generation Rip Saws on it with torque cones. The Rip Saws were drag pipes that had no baffles. The bike with the 103" engine ran perfect with this setup. The reason I switched out the exhaust to a Fat Cat was that I couldn't take the outrageously loud exhaust sound. I rode with the Samsons on for almost 3 years, because the bike performed so well that I didn't want to take a chance of screwing it up by changing the exhaust, but I just couldn't take the sound level any longer.
I read a lot of posts about getting poor performance with drag pipes in the lower rpm range, due to lack of enough back pressure, but I had great performance in all of the rpm range. I don't know if the torque cones helped or not.
