I have another question. My 2006 softail has a stage one kit installed but still has the factory pipes and they sound great.
I'm thinking about getting aftermarket slip-ons and want to know whether it is really necessary for the dealership to recalibrate the motor which costs a bunch of $$? Or can I just slip on the new pipes and call it good?
So what are they talking about having to re-map the motor and all that stuff. By the time they were done it looked like it was going to be about $600 to $800 in labor. Sounded crazy to me.
Dude when you open up both ends of the motor you will get more air into it. If you don't add some fuel to that, you WILL burn valves. Get a Vance & Hines Fuel/Pak easy to install no dyno time and a whole lot lesss costly than a valve job
Rockerhead is right. You need to tune the motor to match the new configuration. A SERT, PCIII, or FuelPak will all get you there with varying degrees of time and money. I prefer the PCIII. You can install it and get it very close without spending money on dyno time. I spent about $250 and it runs great now. I do more mods in the future and can tweak the system myself.
That all makes sense, but I guess what was throwing me is all I am doing is changing the slip on portion of the pipes & baffles and the aftermarket slip on's and baffle appear to be the same interior dimension...so it just seemed the only difference would be the appearance...not so much the function.
Maping everything to match the change made sense to me if I was replacing the whole pipe, but slip ons didn't seem to be that big of a change. Just want to make sure I'm not being bulled over.
If the slip- ons have more sound (Louder)then that means more flow (air) Wich means you should Re Map. However you could install them and then make a short run, then take a look at the plugs. Plugs should be a soft brown, not white. In order to get a good plug read, make a quarter mile run @ full throttle, when you reach the end, throttle back, pull in the clutchand hit the kill switch at the same time. Now look at the plugs.
