    CRF80F: Aftermarket exhaust worth it?

    by Kiwi » Sun Nov 04, 2012 1:59 pm

    I have had good luck with FMF and Pro Circuit headers and mufflers on my different bikes.

    My son has a stock (except for jetting) Honda CRF80F. I'm thinking about upgrading to an aftermarket header and muffler setup such as from FMF. http://www.fmfracing.com/Products/BikeA ... NDA_CRF80F

    Has anyone done such a header/muffler mod on a CRF80F ... and if so, did it make a significant difference in power?

    they definitely flow better than the stock system so they will make more power but it will still be an 80cc motor. ;-) oh, and they weigh less than the stock system and have a nice race tone.

    The bottom line is ... is it worth the $$$?

    that's a wallet question i can't answer. if your rider's skill is exceeding the performance of this bike this exhaust will not make a big enough difference to get more time out of it. if are looking for a bit more power and more cool factor this will accomplish it for you.
