  • FMF Gold Series Pipe, "Fatty Moto"

    FMF Gold Series Pipe, "Fatty Moto"

    robert in NC

    Over all great fit on one bike and not so good on a...

    It's fmf so it's a great product! It does get much hotter than stock and the fmf factory fatty..not sure why although it does not not have as "twisted" and as large of an exhaust chamber as the pro-circuit and fmf factory fatty.. it some how performs just as well. Could be why it gets hotter..?.. the fitment is great on my 98 yz125 although on my 99yz125 (different part #, difference is the way it connect to cylinder) the kicker hit the pipe..that is 1 negative ..although not worth sending back. Also I wish I knew how to keep the fmf gold fatty series to keep from dulling.. maybe it's in the instructions..?.. It definitely increases hp. I would go with the fmf factory fatty if available for your bike..

Dirt Bike Exhaust Systems

Aftermarket dirt bike exhaust systems are among the most popular upgrades that off-road enthusiasts seek. Why? A good exhaust system can add power throughout your bike’s RPM range easier than nearly any other mod. You can also tune it to your style of riding. Need to be stealthy for the hills? Want it wide open for the track? Rocky Mountain ATV/MC has you covered.

An exhaust system is a great way to really add some extra snap to your ride, but since it’s highly visible, it’s also one of the easiest ways to trick out your bike. After all, your friends can’t help but notice when a beefy new exhaust system is installed on your dirt bike! It doesn’t matter if you stick exclusively to the motocross track or the mountain trail, exhaust systems are important.
