hey bigboy
did you dyno any other pipes?

 

On a stock bike the yoshi may have more horsepower, but on a built engine the Yoshi headpipes are too small, and thats where the DMC excels. Hardly anybody keeps their motors stock so you have to look in the long run.

 

not AS of yet will be dong more for customers im sure ....i wll be doin a one with a pro circuit slip on for sure ......
