Performance question regarding SE pipe on the FLHXSE CVO.
« on: April 26, 2011, 06:47:34 PM »

Why should I change the SE pipes that came with the bike? I thought for 30K I shouldn't have  to make any modifications. What are the SE Pipes lacking performance wise??

Depaends on what you want out of the bike.  Most of us remove or eliminate the cat, and use a tuning device. results in less engine heat, corrects the factory lean condition,and adds performance. if your happy with it stock that's great, I would recommend you at least do something to correct the lean condition. That can be as easy as the Xied unit.

In very simple terms.   The tremendous heat generated and the restriction of exhaust flow from the catalytic converter in the head pipe collector next to your right foot!

Just did the Fullsac baffle(s), (2.0) and bought a takeoff headpipe; removed the cat and uploaded the TTS map from Steve at Fullsac (after purchasing the TTS program).  Like day and night.  I was almost embarrased to ride around with the stock sound, plus the heat was getting to be a issue to me.  Running cooler, richer, and a respectable tone puts the smile back on my face.  JMHO.

Humm, I asked Steve if I could have a map for the exact set-up after I bought his 2" baffles last week. He said he only had maps for use with his x-pipes.
Care to email me the map?

The later day CVO models should not be confused with the previous millennium Screaming Eagle big bore and racing use only performance parts!

The later day CVO bikes have big bore power plants but because of world wide exhaust emission laws the Power and Performance of these bikes are severely restricted, some areas of the world have more stringent standards than others! Meaning some areas are more restricted than others, but all are restricted to some extent!

I am sure most Europeans owners will agree that a 96ci Harley engine performs/runs out of the box much better that a 110ci

Gents thanks for all the info....darn who knew.... so here is the Paul Harvey I pick up the bike next week. i'm and american living in germany its a U.S. Specs bike 110.

so most of the stuff I buy will come from the states via mail. but it take forever as we are at the end of the supplyline and buying from the 
German dealers is just too expensive. So what are the steps A-z that I need to take if I want to keep the SE pipes?

When you say "keep the SE pipes"  you have to be more specific. Did you mean the slip-on mufflers or the headpipe (has catalytic built in) or the entire exhaust assembly (headpipe and mufflers)? There are options for all three.

I'd suggest the Fullsac X pipe, baffles (decide if you want the 1.75, 2 or 2.5 baffles) tuner and map from Steve at Fullsac  http://www.fullsac.com/

or, if you want to go the route I (and many other members) have gone, a combination of the above plus the Fueling 574 cams and adjustable push rods (and the cometic gaskets) from Jim at Metal Dragon (hd-dude on this forum)....  his email:  metaldragon1@sbcglobal.net

Then you should end up with something like this....   http://www.cvoharley.com/smf/index.php?topic=44545.0

Wayne G et. al. wow ok well I did not know anything about the headpipe. I initally was referring to the slip on mufflers. However, as I continue to read replies i think I have to do something with the head pipe and the cat converter. Limited expierience 1st HD was 97 FLSTS and I just changed the standard big three carb, cam and slip on SE's. I was happy but never really felt my bike had the big bad uber loud sound. However, it was respectable but not overly loud or didn't make heads turn when you jump on the throttle at a stand still, but I felt performance was solid with a lot of two up riding. What do I want now....... I want it all i want performance but don't want to sync $$$$ into a 30k bike. So I want sound that sound good allows for reasonable long distance comfort i susposed i want to hear the radio as well. So can I just put on slip ons and be done with it? Or, does this cat need to come out? and if I do that what do i get and or what else do i need?

That all sounds good but I don't know that i'd pull the heads with the added cost, just to put a thinner head gasket on and pick up a few HP

How do you Military guys get your bikes serviced in Germany, do you have your own HD mech on the base, I guess not and that you have to deal with a German dealership!  Speak with your colleagues on the base to get there experiences of mods and service work.

As you have a US spec bike I think your best option would be to use the Fullsac stage 1 kit,   http://www.fullsac.com/sleeper-kit-110.html
Steve would send you a tuned map set up for your new mods which you can use with his TTS mastertune dongle.

I say beware because I bought a SERT (TUNER dongle) direct from the US and the jerks Swiss dealerships told be it wasnt compatible with there rolling road computer and I was forced to buy another "European version" which had the same part number. I then gifted the US sert to another US CVOHARLEY site member.

ICE thanks, Yes we military guys must us the Germans or do it on our own. I of the breed that I prefer to ride versus turn a wrench. However, since the euro is kicking the dollars butt I think i'm going to have to change my tune.  Is is possible for me who had never done any major mechanic work an a bike to add the stage 1 kit on my own without screwing something up? And once added am I g2g or do i need to get in dyno'd? oooh and will i void my warranty?

If you search around on this forum your will find a few threads relating to this subject some with a detailed step by step process of changing out the exhaust cores, other threads will tell you a lot about Fullsac and TTS mastertune, I too have never done this job myself as most of this info has surfaced since my 2007 ride was liberated. I am sure you have a friend on base who would have enough experience to help you.
From reading the posts about TTS and Fullsac there guy Steve Cole is very helpful and approachable to help you through the process. As your street glide already has a free flow air filter you wont need to change this, your only need to remove the complete exhaust system, fit the new Fullsac header pipes, drill cut/out the muffler cores and install the Fullsac replacement cores, (you decide which diameter core you want depending on your preferred noise level) refit the mufflers and heat shields. Then download the new software settings with the TTS mastertune and the "Plug and play" map, contact Steve  on this subject. Your bike would not need to be dyno`d. As regards warranty, yes my feeling would be that you would void the warranty, but again you would need to clarify that with the German dealership, so speak with them about your options before you do anything!
If you dont feel confident of doing this job yourself with the help of a mech friend then you will be at the mercy of the German dealer, they would probably send you in the direction of Kess-Tech or Remus exhaust muffler (I dont know what they would suggest about the down pipes) and to use a Power Commander and dyno run.
I guess your military bikes dont have to have regular German TUV (road worthy tests) as you are running with special military plates?
