Motorcycle Repair: pipes, stock pipes, biek

Question
I have an 08 ultra. I have stock pipes on now.I want sum rumble not real loud.What kind of pipes can i put on without having to change anything else?

Answer
your biek came from the factory a little lean. Chenging the pipes with free flowing pipes, which will make the sound you want, will lean it some more. After changing hte pipes you need to check how lean the bike is running and will probably have to remapp
Good luck and happy riding
