I was thinking about getting a Dr. D pipe, am very impressed. Anyway, I know by modding the exhaust, it makes sense to mod the air filter, but I was cleaning mine out the other day, and after looking closely at it, it looks like it is more than capable of taking in enough air. Has anyone else in here piped their yfz without messing with the airbox/air filter? Just curious...

 

yes, i think 2fun just did what DRd reccommended, Airbox lid off and thats it!
