POWERSPORTSWAREHOUSE really that cheap?

Hi guys, searching for parts online I came across this website that has deep discounts on OEM parts. Anybody used them? On the new Yoshimura slip on for Outlander it is literally $100 less than you can get from a dealer. I tried a few OEM part numbers and the pricing seems to good to be legit.
