FMF Factory 4.1 Mufflers are probably the most recognizable four-stroke exhaust mufflers on the planet, and for good reason. These things are pretty damn impressive when it comes to pure bolt-on performance gains, and factoring in how rad they make your bike look, it's easy to see why so many people choose the FMF Factory 4.1 when they're chasing an aftermarket muffler upgrade. When it comes to out-and-out speed and performance, you can't go past the Factory 4.1 Titanium Mufflers, which we carry for the vast majority of recent four-stroke dirt bike models here at MXstore. Most of these will come in the infamous anodized titanium blue colour that FMF is so well known for, although there are some standard coloured titanium options available for selected models.
If you're chasing something a little less expensive than the titanium model but you're still after a strong upgrade, you'll definitely want to check out the FMF Factory 4.1 Stainless Mufflers. We don't carry quite as large a range in the stainless options, but we do cover your most popular models from KTM, Yamaha, Honda, Kawasaki, Suzuki, and Husqvarna. Keep in mind that if you can't find the muffler you're after using our Parts Finder feature, you can also get in touch with our customer service crew, who will be more than happy to try and track down the correct one to suit your bike model.
While the FMF Factory 4.1 Mufflers may set you back a little in the way of your bank account, there's no doubting the impressive results that these beauties bring to your riding, so they're an investment that is well worth it. Throw in the fact that MXstore will cover the cost of shipping your Factory 4.1 Muffler to you, no matter where you are in Australia, and you're definitely on to a winning combination. Check out the range and get your bike the upgrade it deserves today!
