Do I need one? and if so what do I need to buy?

Now to give you some info to help you answer.

My Harley has a carb, so after I had the Sampsons put on I had it re-jetted and dyno'd and everything has been fine since. carbs are easy I have no experience with mapping.

I've got an '02 speedy, I'm putting a Zard slipon on it, and I'm not planning any other performance mods other than maybe a K&N.


Whaddaya think?

I've looked at the site, I was just wondereing whether I needed the whole $500+ setup or something cheaper.

As I said above, I'm really not planning to mod the speedy much more than the pipe and maybe a K&N filter.
