I have a 2013 CVO RG- was going to get the Fullsac DX header pipe but the local Harley dealer says just get a HD 2009 stock cat-less pipe.  What is the difference between the 2 header pipes?  Any thoughts?? Planning on putting on the V&H high output slip- ons... Thanks for any input...

Well the dealer I think has a screw loose,  your O2 sensors would need to have a bung welded to the 09 header.  You would have to make sure the are welded in just the correct location and depth also.  If the are at the wrong angle and are to close to each other the wont work properly. 

People that have a jig already set up to do it don't have a problem. 

Going to the fullsac set up has a lot more benefits due to the design itself.  It to there web site and just read about it and also just do a search on here.   Just look at the stage 1 set up and look at the benefits they show.  Big Bang for the buck in my opinion.  That's what I am getting as soon as I am done building my new garage.

Thanks for the info... however, according to the dealer they have done  this same set-up (2009 stock pipe) many times... One possible concern re the DX is that the pipe under the frame is a full pipe vs the cramped stock pipe- possible the larger and lower pipe might hit a speed bump or something similar??

[tweeter13]

I don't think it changed anything.  He still has the C pipe which uses the old cross over pipe.  If you cal down there and talk to them they will explain it all to you.  Very nice people.  I just wish I was done with this garage.  I want this bad I can taste it. Lol.   

I think the DX pipe he changed the angle just a little bit so the pipe would not need to be flattened out.  If you do a search on fullsac DX I think you read about it or its on their web site I bet.   But talk to them their customer service is awesome and if you mention that your a cvo Harley member here they give you a discount as well.  I and Steve has got their map for the tts system tune right on for our bikes.  And with the tts you can hook up your lap top and double check the tune and do any small adjustment in your riding area if its needed if you feel it needs it after you get every,thing installed. 

We're you planning on doing the install yourself?   I am going to do it myself.

I've made mention of this in another thread, but my builder/tuner doesn't like the Fullsac for lower end tq because it has a smaller collector area. He's convinced me to go back to the OEM catless headpipe, which I am in the process of doing- just having one ceramic coated now.

I will post dyno sheet from before with the Fullsac head pipe, and after with the OEM one on, and I'm confident I will see a gain in tq between 1500-2500 rpms, which is where I'm down compared to other builds he's done where he has used the OEM pipe.

However, if you're looking for higher end hp, it would appear the Fullsac has the advantage.

BTW, I noticed Jackpot now has a "XXX" version of their headpipe which has a much bigger collector. Kinda supports the theory that a bigger collector is better.

The bigger collector is beneficial if you're planning on increasing displacement and going with a big cam.  If you're only planning a Stage 1 and maybe a 575 or so cam, the standard Jackpot is a fantastic choice.

Lots of questions arise.
How much work are you doing?
What kind of relationship do younhave with the dealer?
etc etc
Best to CALL 928 505 2912 and ask for Steve
Go to the source as they say!d

Just installed a DX pipe, and it does hang a bit lower than the stock pipe, but not lower than the frame.

Thanks for all the info here - not going to do this myself as I have no mechanical ability... Local dealer is pretty good, says the dyno numbers using stock (2009 catless) are same/better than V&H power duals which was option no. 2.  I'll give Fullsac a call but you can only be so impartial re your own product.  My main concern was the dealer's suggestion of getting a 2009 stock pipe for my 2013 CVO.

Lots of folks used the 2009 catless headpipe from the standard models back in 2009 on their 2009 CVO's that came with the catalyst.  In 2010 all the bikes came with catalysts, and the location and size of the bungs for the new heated oxygen sensors was changed significantly.  He can't just throw a stock 2009 headpipe on your 2013 unless he also plans to address the different size and type of oxygen sensors, and the locations.  In other words, you need him to give you a whole lot more detailed information before you agree to his proposal.  If he plans to add the proper bungs in the proper locations, it might be OK.  If he plans to just eliminate the oxygen sensors and run open loop all the time, you need to find someone more enlightened to do your work.  You do not want to eliminate the closed loop engine management capabilities on a street bike, in my not-so-humble opinion.

btw, some of the experts will tell you that even if they add the proper bungs for the late model sensors you may still have tuning issues due to cross talk between the two cylinders.

HKHabe,

I'm running a 2011 Decatted header with V&H Hi Outputs with. PowerCommander V that I bought preprogrammed from www.fuelmoto.com. Sounds great and runs great. You're going to hear a lot of opinions but I'm running this setup without any of the scary stuff you'll be lead to believe.

Order you V&H Hi Output and your PCV from Fuelmoto and when they arrive spend about 2 easy hours of your life and install it all yourself. Cut a batch out of your header where the 2 pipes collect into one (3"x5") and the knock out the cat with a chisel. Then take the header and the batch to your local muffler shop and have them weld back in the back. probably $30.

Reinstall the header, install your new mufflers and plug in the PCV and go riding.

It is super easy to do yourself. Trust me! Or buy new headers, pipes, tuner, have the dealer install it all and a dyno tune (so they can run the crap out of your bike).

Willy, the reason you can run that headpipe on a later model year is obvious; you aren't using the oxygen sensors with a PC-V (it eliminates them).  So obviously there will be no cross talk because there is no sensor data.

Yes, we ran open loop for the first 103 years Harley existed, and we survived.  But to me it makes absolutely no sense to throw away the biggest engine management improvement Harley has installed in those 100 plus years.

Properly tuned they run just fine.
I believe in "moving forward" not backward with the electronics we have now.
In fact, the stock bikes run pretty good right out of the box.

my 2013 SERG made 118.2 trq with the fullsac DX, se tuner & some dyno time. local dealer did the tune and he stated that it was the most trq he has ever got out of a stock 110 with just a pipe & tune. ps used fullsac 2.25 baffles. very happy... for now
