What do you guys have to say about these two units? Just picked up a FatBoy Lo in Denim Black and I want to add pipes, air cleaner and so on. Do these units really work?

 

Thundermax all the way better IMO the Accel unit is a piggybacck module. I have a friend with one and he loves it

 

Since you're new I'll help.

There's a button on the right side of the page that says 'search this forum'

Please search for 'stage one' etc. before starting yet another thread on this. Lots of info on the 96ci motors

There's also this:Thundermax or Accel SLM
