I want to remove my mufflers off of my 2011 fat boy and extend the pipes about the same length as stock. will I have to to do some kind of ecu tuning or will it be ok ?

Are you going to just run long headers?

Who makes the headers?

What other changes have you done?

Are you still under warranty?

 

Sorry we can't read Ur mind.
Are U talking so new slip ons or just adding more straight baffleless pipes?.

U should still have more warranty left so I wouldn't run just straight pipe, Even without a warranty I wouldn't recommend that.

It really hurts U low end TQ, and will just make a LOT of noise, that Ur neighbors and Ur ears wont like.

Either way as we've said thousands of times in here before, Pipes only U don't need to do anything to Ur motor, But U'll still be running EPA lean which most of us don't like.

 

yea I was just planning on taking the slip ons off and adding some more straight pipe so they won't be so short an leaving the slip ons off.

still in warranty

I do have a open air filter I plan on putting on. this is just a short term thing until I can buy the pipes I want. I say no more than 3-4 months. I could put some baffles in them but I was thinking strait pipe.

nothing has been done to engine

 

Just so you know that by running and open exhaust no baffles. You run a chance of sucking a valve while running in cold weather, you bike will pop like crazy. I would just stay stock until you have the cash to get the pipes you want and and do the A/C and an ECM Update or tuner at the same time. Just not worth the risk.

 

If you put the A/C on and run straight pipes, you will be way too lean. I wouldn't recommend it.

Best thing you can do is wait the few months and do em all together and get it tuned. Thats what I did and do not regret it one bit.

 

Well, think they said..

 

What he said. If you are only a couple months from getting a complete and proper system then why risk doing something that could hurt your scoot in the meantime?
