do you run the hrc kit with the spark arrestor on the 06's or not?

The HRC kit retains the spark arrestor, but you pull the insert out of it. You have the choice of installing the AMA difuser or leaving it out. I just started installing the kit on my '07 tonight, and I might leave the difuser out. Depends on how it sounds.
