I know there is a huge amount of information on here and have been reading for a while but am still confused so decided to ask directly!

I have a 2005 fatboy that I bought used. It came with V&H big shot staggered and big sucker. It does not have any after market fuel management system so I am presuming it has a stage 1 download although I do not know for sure. Bike runs fine and I love it of course.

I've had it a couple of years and am thinking about changing out the exhaust. I am looking at V&H big radius 2 into 2.

Questions:
1. Will I need to have the bike retuned if I change out the exhaust? If so I presume I would have to go to the dealer?
2. Is it going to be worth my while getting a Power Commander (or other system) although I really don't know much about how these work and would probably worry I would mess something up!!

Really I would like to buy the exhaust, put it on and not have to do anything else. Is that realistic expectation?

Thanks
Dave

 

Id say youd probably be ok...why the change? the big shots will perform better. is yours the factory 95"? Id keep the pipes u got or go with a 2-1 and throw some better cams in there, tts and full dyno tune. Ud be amazed at how well itll run after that.... just a thought though!
