hi guys. i was out today driving, not riding, arrrggg,.. anyway i saw&heard a 1200c looking beaut , but what got my attention was the sound. it sounded alot  more meaty than a1200, absolutley fantastic if  ido say so. anyway can it be taken out to a 1340,to be able to make this sort of sound? or was it just pipes. it wasnt overly loud, just perfect iwould say . its just that it sounded alot bigger if you know what i mean. any ideas?

It was probably me. You didn't say hi.

Gag aside, I'd say it was a set of Vance & Hynes or S&S pipes or similar.

My work window sees a lot of Harleys go buy passing through to the Ranges, and the Sportsters generally sound better than some of the granny glides etc.

Probably just a good exhaust, my 883c sounds loud and throaty with the 2.5 Rush slipons

yeah maybe just good pipes'''' but can the 1200 be taken out to 1340cc ... same as 883-1200?

sorry not sure about your question but my 07 1200custom can be heard from a whole street over and ppl def hear me coming and i think mine sounds rather deep and chunky, i have S&S slipons

I agree go the s&s slipons best for power, louder then the screaming eagles,  look stock for the blue boys. If you go the full header way for eg short shots or side shots v&h you will lose power. my 2 cents

I got the Screaming Eagles on my 2010 XL1200C and I think they sound pretty good, I've only done about 900ks all up, so they arnt even run in yet, and the Mrs reckons she can hear me a few streets away.....

1200=74cube
1250=76cube
1450=88cube
no you cant go to 1340=80 cube you can fit 1250 barrels with no machining but there not hd barrels,and if you want to machine the cases you can bolt up some 88cube barrels !!!!!!!!!!!!!111

HI all,

Im new to Harleys and this forum and while waiting for my bike to arrive have been checking out sporty gear and particularly pipes.

I have spoken to a few folks and cant seem to find the definitive answer abut pipes.

I am considering s+s slipons and have been told that a high flo AC will be best and then i read other posts and people say that you have to put a new ecm in.

My dealer has said he can get the baffles out of the stock pipes for about 600 bucks and it will run fine.

I guess i just dont wanna go the s+s and then have to dick around and pay more cash for fuel mods dyno etc. if things dont run right.

Seems everyone has a different opinion on this.

can any one give me some solid advice on this issue?

Im down here in Canberra cant wait to get out on the road.

cheers

As soon as you Change the Exhaust to a free Flowing system in any way. YOU must add more Fuel. and beacuse it is EFI, It's a ECU Up Grade, there is no way out of it,,,,
The guys that are Drilling their Muflers without up grading the ECU are looking for trouble. Witout the Extra Fuel the Bike will Run Lean and in the right condisions,, will damage their Engines

Hey man thanks heaps.
I rang Rollies and John also confirmed what you said.
Basically i dont want to do something to my new scoot thats gonna cause problems down the line.
so i guess i save some dough for when the Iron finally gets.
Im thinking about the powermax as it can be mapped at dyno and is a reasonable price any thoughts?
Had a look at the vpw website too, thinking bout those new pegs.
thanks again.

Your in Canberra,,,, Talk to Peter at Pulford Race Engines ,,He has a Dyno and Knows how to tune it right.

Like i said I have the SE slip ons and find them ok i had them put on when I got the bike three weeks ago,i've done 1400km now and am looking at doing the AC and ECU upgrade as over the last week I have noticed a bit of snap crackle and pop on decel. I'm thinking of using the fuel pak for the ECU upgrade. If any one has installed the fuel pak a quick question ....is it overly hard as I tend to be all thumbs when it comes to that sort of thing.

So whats with all the info on the net about doing pipes only no flash or tuner needed. I was just about to drill mine or get some slip ons.  Im gonna wait and save up and do the pipes intake and tuner all at once I dont want to risk wrecking anything. Glad I read this post......or is someone gonna confuse me more ????

The Honset anwser is that it's all bullshit.....If you open up any Exhaust to flow at a faster rate you must add FUEL.  By not adding extra Fuel your also robbing your self of Power,

Harleys in Aust are Factory Tuned to meet EPA Laws , that means the the Bike is Jetted or Tuned to produce Low Emisions , the way that they do that is to run the bike on the border line of Lean with a Standard Choked up Mufflers.  

My Bike is 06  1200 Custom ,the last of the Carbie Models. I think the Standard Jet in the CV Carbie is 92, I have Hooker Trouble and a Corsair Air Cleaner .Standard the Bike makes 77 HP . The Bike now Needs a 115 Jet Beacuse of the Pipes and Air Cleaner  It now makes 105 HP.

You know the whole idear of running a loud Exhaust is to make more HP, Not to piss off your neighbours or look like a Bad Ass Biker

Ok a simple Check is Before you Change or Drill out your Mufflers, take your Bike down the End of your Street, TAKE OFF, once your a fair speed switch off the Engine and Roll to a Stop. Pull out one of your Spark Plugs and have a look at the Eletrode on the End of the Plug . It should be Brown or Black Colour,depending on the Weather of the Day.

Now fit you New Exhaust , Mufflers or Drill Out your Stock ones, then do the same Test,, If the Eletrode is Light Brown or Gray or even White , Your Bike is Lean. and by the way White is BAD, See how you go

 

What Walka has said is basically the same as what the guys from rollies speed shop told me as well. Awesome tip about checking the plugs that is golden.

I was also at chopper works today ( yes im obsessed no bike to ride as yet ) and after talking to the guys there, the deal seems to be that if you put slip ons on there is a fair chance that nothing untoward will happen or cause any major dramas and the chopper works guys seemed to think that the new 010 ecm should be able to work with slip ons a bit to make the bike run as well as it can. but once you godifferent pipes and a high flow AC then a fuel mod and dyno is the best idea.

Then all bits will be tuned to your bike you'll have more power and the bike will sound better.

they guys at chopper works did say though that they had a lot of trouble trying to fit the power commander etc . they said they tried a number of the most popular fuelpaks and there is not a lot of room on the 883 iron or nightster so it was quite a difficult task to get one to fit.

they told me that maybe the Se pro tuner would be a better idea as its a genuine part and will fit into the bike easier a tad more expensive.

They guys also said that the V+H short shot staggered are hard pipes to tune with.

Im now thinking new pipes first and then AC and fuel mod in a few months when cashed up. i must say i like some of the reinhart pipes.

Im just after a nice harley sound and the best for the bike so it runs well.

Thanks Walka for your awesome advice too man today has been a real learning curve and everyones help has made deciding what to do and working out a budget a lot easier.

cheers !!

 

 

I found this on the xl forums. seems like a good rundown.

You mention that you want the best bang for the buck, but you really have to consider a few points. Are you the type that likes to tinker? How likely are you to do mods other then changing the A/C and slipons? Are you the type that wants every last horsepower out of the bike?

Since this seems to come up fairly often around here...The choices break down like this I believe:

Harley Remap ($100 - 200??) - Available at local dealer
Pro's - Real easy to do...drive bike to dealer. Cheapest one time solution. Some are reporting extremely good results. Can raise the Rev limiter (and possibly change the timing??)
Con's - One size fits all...well sorta. They have only a handful of maps to chose from, pick the closet one to your setup. Have to pay the piper every time you make a significant change. Your stuck with what they gave you.

Fuel Adders ($200-$300) - like Power Commanders, SE Race Fueler, Cobra, V&H Fuel Pack (I'm probably missing some)
Pro's - Relatively easy to fiddle with (most don't require a computer to setup). Relatively cost effective solution. Will work with an extremely wide variety of setups.
Con's - It will take a little fiddling (depending on which model, some do have canned maps). Many of these will not offer very fine tuning (For example the SERF only has three RPM points to adjust the mixture on). None of these will raise the RPM limit or adjust the timing map (actually I think there is a add-on for the Power Commander to change the Rev limiter).

SE Race Tuner ($350-400) - I classify this as it's own category.
Pro's - Easy setup out of box with a handful of canned maps. Very adjustable fuel and ignition maps. Rev Limiter adjustable. It's cool to hook your bike to a computer?
Con's - Unit "marries" itself to the bike's ECM (meaning if you sell the bike you need to send the unit along with the bike). To really setup a custom application will take 4-6 hours on a Dyno (this is according to NRHS and two local dealers).

Custom ECM's ($500 - on up) - Daytona Twin Tec, I believe the Thundermax Autotune falls into this category (maybe MegaSquirt at some point)
Pro's - Complete control of everything. Possible to do closed loop EFI over the entire band. Most adjust ability.
Con's - Most complicated. Potentially requiring the most fiddling. Not likely to get any warranty work done by local dealer after install.

Anyways, I've been researching some of this for a while and just brain dumped. I'm sure I'll be corrected were I brain farted instead of dumped... I'll update this list as well as people add other ideas.

There's a thousand different opinions floating around on all this. They will lean out and they do run hotter from experience...

I'm almost of the thinking that the ECM should be able to compensate for a change of an air cleaner OR pipes (especially slip-on mufflers). Hell they're shipped to manage changes in altitude from Vancouver's cold sea-level to the really cold and altitude of the Rocky Mountains, to Florida or Californian heat as well.

There's an emerging school of thought that the fuel adders and expensive remaps are just money spinners and the ECM should take care of an air cleaner and pipe mod though no one is brave enough to experiment with these though.

These 2 links provide some more great info as to why and how to do these mods

rock on!

Hi there, i have an 07 custom sporty had the S&S pipes on it for about 17000klms bike currently has just clicked over 18k and the only issue i have is occassional decel pop but you can also get that from shit fuel,otherwise it runs great heaps of power etc, i add a little octane booster every second tank or so and generally dont pop but depends how you ride. i ride pretty hard but also just cruise and if you back off from high revs it'll do it anyway, just my 2 cents

Octane Boost only works with Engines that have High Comp,,,,,,,,, Your wasting you money putting that crap in it,,, If it's Poping it needs more Fuel, not more Lead .. You think you Bike is fast now , tune the thing right and you will see how much power and faster it can be
