Aftermarket dirt bike mufflers don't come much better than the FMF Factory 4.1 Titanium Mufflers. Perhaps one of the most recognizable mufflers in the entire industry, largely thanks to the beautiful anodized titanium material, there's a good reason why racers all over the world go mad to chuck these beauties on their bikes. Not only do these things look a million bucks, they're also one of the best performance upgrades that you can simply bolt on to your four-stroke machine, so if you're chasing speed and power upgrades, you're definitely in the right place. Titanium is one of the lightest materials in the industry, so the weight savings alone you get from an FMF Factory 4.1 Titanium Muffler is going to get you on the front foot.
Here at MXstore we stock Factory 4.1 Titanium Mufflers for the majority of your popular four-stroke dirt bike models from Honda, Kawasaki, KTM, Yamaha, Suzuki, and Husqvarna, so we should have you covered if you're riding a newish model race bike. While they may not be the cheapest exhaust upgrade out there on the market, they're certainly one of the most useful, so if you're looking to get results back from your investment, it'd be hard to go past the Factory 4.1 Titanium mufflers. We've tried to sweeten the deal a little by offering free standard shipping on all of our FMF Exhausts, so at least you know your money is being invested into your bike and not wasted on covering any additional freight charges.
We chucked one of these on our 2017 Honda CRF450R Project Bike, and we were completely astounded at the immediate response we felt the first time we took it out riding. Throttle response and bottom end torque coming out of corners was amazing, and it's safe to say we definitely fell in love with the sound of it. Check out our handy little how-to video below where we talk you through the steps involved with installing one of these on your dirt bike.
