HMF is my preference, but Sparks, Yosh, duncan, are all good systems.

There are a few good systems out there. It all comes down to what you want to do. If you are not going to work the motor up alot then a slip on will be fine but, if you are going to do alot then buy a full. Like it was aleady said let us know how it turns out.
