Would I need to map the exhaust system if I buy slip on mufflers for a 2005 Harley Davidson Ultra Classic MC?
EDIT:...As if I really care, but why 2 thumbs down???...just because I hate Power Commanders.....read my details as to why. I tune bikes daily for a living...I know what works and what doesn't.....oh well.
Email me through my profile and I can give you more and better details. If you have any questions...just ask.
DO NOT....use a POWER COMMANDER!!!!......USE THE SCREAMIN EAGLE SUPER TUNER!!!!
You should SERIOUSLY add a HI-FLO AIR CLEANER as well.....the stock a/c is the single most power restrictive part on the bike!!!.....read on for info regarding tuning.....
This is a group of clips from similar answers....
They guys you were talking to are kind of right. With the pipes you are looking at, the bike really does need to have a hi-flo air cleaner put on. The dramatic decrease in restriction and the short length are the reason. Shorter pipes generally cause a drop in power in the low and mid-range, but can be compensated for somewhat by adding a set of Samson Torque Cones. The air cleaner will be needed to let more air in also to help compensate for the increase in exhaust flow. The Screamin Eagle air cleaner is ok, but the Arlen Ness Big Sucker (get the Stage 2 version) is better and about the same price. The S/E uses a shallow, dry filter material similar to a fiber glass mat, the Big Sucker uses a deeper K&N filter that flows considerably more air than the S/E. The stock HD air cleaner is THE most power restricting part on the bike. If you pull off the cover and look at the element, you will see why...it literally starves the engine for air, the reason for this from the factory...EPA NOISE pollution restrictions.
Now this is the MAJOR factor in the situation....DO NOT let anyone talk you into a Power Commander or Vance & Hines Fuel Pak, or ANY type of "piggy back"....FUEL...module!!!
You want the Screamin Eagle Super Tuner!!!
There are several reasons for this.
1. There is almost no room on a Softail to mount an add-on module, it basically get jammed and stuffed under the seat. "piggy back" modules plug in-line between the bikes computer and the wire harness, they are big and bulky and create extra wiring that is a BITCH to mount, route and work around.
2. They do not do anything except control fuel, they have no timing or rev limit adjustments. The Power Commander 5 for 09-up bikes does have an Auto-Tune module that will allow the system to adjust the fuel by itself while you ride...BUT it is an additional couple hundred dollars, and you have to add yet another module to allow for timing adjustments...now you have 2 additional modules to try and figure how and where to mount. All together you will end up having arouns $1000 in modules.
The Screamin Eagle Super Tuner is basically nothing but software that reprograms the stock computer. It is a box that goes between 2 cables that link the bike to a PC. Once the computer is programmed and mapped on the dyno, you unplug it....nothing to mount. DO NOT LOSE THE BOX!!!!....if you do and need further tuning in the future for mods done later, you will have to buy another Tuner. The Tuner, once plugged in to a bike is "married" to that bike only and will not work on any other bikes. The Super Tuner has virtually unlimited tuning capabilites. It will allow for fuel mapping, accelerator pump feature for better throttle response, fully adjustable rev limit (do not rev a Softail past 6200, past that, the balancers spin too fast and can fly apart and destroy the engine), fully adjustable timing advance and curve tables, etc. I was amazed at what this thing can do when I was trained on it.
Having the timing properly set makes all the difference in the world. We tested bikes with stock timing and rev limits that had the fuel dialed in perfect for max power, then loaded in performance timing maps and had gains of 5-15 hp & tq.
And there is one more benefit to the Super Tuner compared to the others....The Tuner is about $400, the same as the others, bt no added expenses from add-on modules...its all built in.
Doing all of this, and having the bike tuned, WILL make it run cooler!!! The Twin Cams run hotter than the older Evo's like Mike has. The reasons are being tuned VERY lean for EPA standards and the Twin Cams use oil jets under the pistons. These jets squirt oil onto the bottom of the piston to help cool it. Stock engines run sooooo lean that they cause excessive heat.....here is the oxymoron....because they are so lean, HD designed the oil jets to cool the pistons....what actually happens is the pistons HEAT the oil!!!....tune the engine, richen it up, and the piston cools down, now, the oil can do its job and cool the piston....double cooling effect. Proper tuning will decreae oil temp by as much as 20-25 degress and promote longer, more reliable engine life...and you will FEEL the power increase.....generally, depending on the bike, combination of pipes and air cleaner, and how good the guy tuning the bike is, you can expect 10-15 hp & tq increase.
Here are my recommendations on oils...
As much I love HD....I hate to say it, but HD doesn't know SH*T about synthetic oil. THE BEST 3 SYNTHETICS FOR A HARLEY ARE......#1-AMSOIL, #2-LUCAS, #3-MOBIL1(which is recommended by S&S). I have been working on HD's and building performance engines, drag racing and dyno tuning for 20 years and have been running Amsoil for years, but have recently switched over to Lucas because it is just as good, but a little cheaper. AND THEY DO NOT AND WILL NOT VOID YOUR WARRANTY.
FIRST OFF.........DO NOT RUN HD SYN3.....IT'S JUNK.........I AM A CERTIFIED HD TECH, AND I WILL TELL YOU FIRST HAND....HD DOESN'T KNOW JACK ABOUT OILS!!!!!!!!!
For deacdes, HD said to never run synthetic in their engines, their reason....it will cause the bearings to "skate".........but ask anyone on the drag strip running a top fuel 800+ HP engine what they run.......FULL SYNTHETIC.......their bearings don't skate!!! By popular demand of the public, HD finally released their SYN3 back in the early 2000's......manufactured by Sunoco. SO........As the other guys have said, synthetic does make your engine run cooler and lubricates much better than standard oil. Some say it is ok to run the same synthetic in the primary as you do the engine, but I tend to disagree, Barnett Clutches DO NOT like synthetics, synthetic breaks down the friction material, stick HD's Formula + for you bike if it still has the stock clutch, if the clutch has been replaced, run any high quality standard petroleum MOTORCYCLE 20/50.....or even ATF auto trans fluid (that's what I run in my personal bikes.......but NEVER use that same oil in the trans. HD says you can, but it makes the trans hard to shift and noisy......run minimum 75/90 gear oil......the absolute hands down best trans oil on the market is RED LINE HEAVY full synthetic Shockproof ...it will make your trans runs smoother, quiter and shift easier.
Agree with you……..as another one of the little people, I’ll buy the “so-called” scientific explanation for global warming when they can establish the link between my Harley-Davidson exhaust and the shrinking ice cap on the planet Mars! I suggest there are larger solar cycles at work and all of the earthly hand-wringing is related more to the next government funding cycle than reality.

hahaha funny lol
ride on.lol
