What is the diameter of the headpipes that come with the new Freedoms?  Are they the same as stock or Rineharts?  If Freedom has a good thing going with these mufflers, maybe they should consider making them fit the stock headers so you could just add the muffs?

The headers are stepped, at the muffler they are 2 1/2". They won't fit any others.

Jim,

Was any tune done to the bike while it was bone stock?   If not it really isn't a fair comparison, it would be better to then compare the numbers to a D&D or Rineharts with SERT to get a true opinion on how much better they show.   I am not in any way putting the pipes down I am sure they are good, but people need to compare apples to apples vs. untuned to tuned.

Harry;
The bike was stock except a stage 1 AC kit as I mentioned in the post. I posted it to show that these pipes do perform. As a comparison most 110" with RH's or other pipes are getting numbers that are close to what these have shown. The increases seen here are similiar if not a bit better than most of us have seen with an exhaust system and Race tuner or PCIII.

Jim,

Sounds like a good alternative depending on taste of sound and or look.   The numbers are as good if not slightly better than most of the dyno's were seeing with true duals on the FLH's.   Generally Rineharts are 86-95 hp and 105-115 torque on the average.   Some might be slightly higher or lower depending on the day / dyno / tuner etc. 
Who did the tune with the SERT in this case, thought that Brad was only doing the DTT and Power Commander?  Might be another place people can look to get some help with the SERT in that area.

Brad did the tune, He is only using the SERT 07 & up bikes to retian the o2 sensors. He has told me that he can get a much better tune on them with it over the PCIII.

That is good to know that Brad will tune with the Race Tuner.   Do you know if he is taking advantage of the closed loop system or by-passing it and just setting up the map in open mode like he would with a power commander since he has no eliminators for the 07's?

He is using it in closed loop.

Jim,

Thanks good to know

As an FYI, I rode with Andy (AK) yesterday and checked out the pipes.  They are throaty but definitely a LOT quieter than the Thunderheader that came off of the bike.  Volume is slightly louder than SE slip-ons.  Riding behind him was a pleasure.  We switched bikes and it is nice.  Bike was very smooth accelerating with no popping at all while slowing down (good job Jim).  I could hear the radio and my wife really enjoyed not being overpowered by noise like she usually is (both of my bikes have the Thunderheaders as well).

Brad said he can do so much more with a SERT than he can with the PC III.  He changes the cold idle start, raises the rev limiter, and thats before he starts the dyno tune.
