Im getting a slip on for my bike and have read different opions on what to do with it. If I have just a slip on, should I get an after market intake or is one not really needed (I've heard both but want to see what you guys have to say). Also, if I modify to full exhaust in the future, does that change if there is anything else that needs to be done? When does the pcm thing come in? thanks for the input

 

I have found that any performance mod requires the bike to be setup / dyno tuned to take atvantage of the changes, exhaust and air filters. If you can, get the Power Commander. To be honest, if I start over, that would be my first mod followed by full ehaust (slip-on if buget is tight) and then air filters.
