    Awesome silencer

    Super quiet made power delivery smoother and definitely an increase in power in bottom to mid range. Only negative is it is a lot bigger than other silencers but I love it

    CR500AF

    We recently rebuilt the 1990 CR500 engine in our 2010 crf250 frame and noticed the reeds were chipped on the tips. We put these in and it runs great.

  • FMF Power Core IV S/A Silencer

    FMF Power Core IV S/A Silencer

    Stop debating buying the Power Core 4- JUST DO IT!

    I spent a good week reviewing website reviews, watching You Tube videos, talking to dealers, etc. There are several options and manufacturers dealing with after market exhaust. The FMF Power Core 4 is absolutely AWESOME. The videos do not do justice to the sound this thing puts out! It went from sounding like a kitten to an angry lion in about 20 minutes of EASY installation. However, don't expect this to totally give you balls to the wall power. It did increase the performance somewhat and I am very pleased. The immediate change was just the awesome sound and rumble this thing puts out. My TTR is now as loud, or louder, than my brother's YZ! Highly recommended!
