What People Are Saying About Louthan Competition

  • I just wanted to thank you for the great job you did on my Yamaha Raptor head. It looks great and performs even better. I'll recommend you highly when my friends want their bikes done. I'll send you a pic of my bike soon. Thanks!

  • Rob, Thanks very much for building the set of World Products heads, My ET's went from 13.50 to 12.27 and mph from 101 to 144.8 and there is still more potential! Thanks!
