  • FMF Power Core 4 Hex S/A Silencer

    FMF Power Core 4 Hex S/A Silencer

    Raymond in WY

    Good sound, good price

    My crf450x now has a similar tone to my friends crf450r, the rhythm is still different due to the r's more aggressive cam. The stock exhaust was restrictive and very quiet, so I removed the baffle from the stock muffler and it was too loud. This FMF pipe is a happy medium between the two. One thing I did not like was where the mid-pipe connects to the header pipe, I would like to have a metal clamp similar to the stock one instead of using high temp silicone. But overall the fit was good.

    The Best!

    I use this pipe with the FMF power bomb head pipe on my 400ex. It keeps the sound legal here in WI and still sounds great.

    Improved Throttle Response

    Great fit and finish. Super easy to install with OEM header. Slightly louder but not too bad. I have the spark arrestor inserted for trail riding and the bike revs much quicker on the low end which helps acceleration. No noticeable change to mid or top end power. I am uncertain if power output has improved but the acceleration is smoother and quicker off idle which makes it a great product. I would not hesitate to buy another one.
