ok my hd dealer suggests the following, because i dont plan on big mods, to use the following procedure to change pipes,(for sound) air cleaner assembly for flow and ad what is called a cart? part #32926-03b not looking for big gains here just improve sound from the quiet i have.
any input
thanks. p.s. pipes  would be screamin eagle part # 64903-99 slash cut one piece. [smiley=nixweiss.gif]

I'd go with new version of the Rinehart True Duals, SERT, and the new K&N Filter part # rk-3909 if it was me and I was trying not to have to buy things twice......... [smiley=xyxthumbs.gif]

[RATKING]

I would recommend the following, having had great results on my own SERK.  

 1) The stock air cleaner system is very restrictive and has to go.  The Screaming Eagle
     unit is fine, I went with the Arlen Ness Big Sucker, as it has a better contour into the
     throttle body and an internal (hidden) breather system.

 2) The stock mufflers have to go.  There is nothing wrong with the stock dual/shared pipe
     arrangement, they actually work pretty darn good.  The real problem is the mufflers, they
     are too restrictive.  I would run the SE mufflers you listed (do not get the newer SE II
     mufflers, as they do not perform as well), or a Kerker or Vance & Hines slip-ons.  I went
     with the Vance & Hines Ovals;  great look, sound and performance.  But again, everyone
     has an opinion.  The V&H Ovals were a new release at the time, and when I was
     investigating, the company rep told me they had higher flow values and would work
     great with the 103 engine.

 3) Obviously with the improvements on engine throughput, you will have to modify your fuel
     and ignition maps.  Yes the new "cartridge" or factory download will help, but as the
     MOCO is installing it on a street machine, it still has to be politically correct (read EPA
     friendly).  The fuel maps will be leaner, and the ignition curves slower as it still has to be
     "street legal".  You will not get the same performance on a factory download as you
     would with a canned map from the Screaming Eagle Race Tuner.  These fuel and ignition
     maps are much more aggressive, and your bike will perform much better.  Plus, it is easily
     modified for any changes you make to the bike later.  I would put the money you would
     spend for a new catridge or factory down load towards the price of a SERT.  You can buy
     SERTs on EBAY for $350 all day long.

xocyber,

If you are looking to go with the Rhinehart True Dual System.

I have a complete set of the Freedom Cycle Rhinehart True Dual System. Look through past threads on the Freedom Cycle Rhienharts.

The true duals have apprx. 2,800 miles on them and are in excellent shape, includes all heat shileds and the Chrome End Caps.

They were on a reworked SE 103" put out 108.6 hp and 117 lb ft Torque.

Asking $575.00 plus shipping pipes are in Phoenix.
