If you look in the air box there is a filter on front of the replacable filter. We removed that, and cut out the whole front of the box. It sounds and performs great.

Removing the charcoal filter is a pretty common thing for us to do, but I wouldn't cut my airbox like that. Now you are drawing in more hot air from the engine bay instead of it pulling from the cooler air space behind the kidney grills.
