Im a trail/track rider. I want better midrange/topend power. What are the best mods to do to these bikes apart from DRD exhaust.

A good exhaust, jetting and gearing should get you enough. If not a high compression piston works well, I prefer a piston to cams. Some people think a H/C piston causes you to loose top end but I have not found that to be the case on the YZ-450F, the gains outway the loses in my opinion.
