    Question 250EX exhaust

    I need help on buying a new exhaust system for my EX. There is the Yoshimura slip on, White Brothers R4 S-Bend, and the Big Gun Complete Race or Quiet system. Which one would give out more horsepower and will last the longest.

    White Bros. has the reputation for letting your engine produce the maximum amount of HP. And they have a great record of durability. I would definately go with the R4.

    out of a Chaparral catalog. You can get your free catalog at www.chaparral-racing.com
    they have different numbers of catalogs so I don't know if they are the same.

    We are currently testing a Yoshimura silencer on a 2001 250ex. So far the quality is flawless, the power smooth and far reaching. I have one on my 400ex and have experienced zero problems. The quality is un matched. Power delivery is very close with all pipes I have tested. I will post more as we get through our testing period or feel free to contact me via e mail or call the store at 877-264-3409

    Thanks
    Terry
