FMF

In the early 1970s, California native Don Elmer was an expert wrench for local friends and racers, helping to make their bikes the fastest on the track. The secret was in the exhaust systems, and Elmer had the process and products perfected to make any bike fly. It didn’t take long for word to get out, and soon, “Uncle Donnie’s Flying Machine Factory,” or FMF, for short, was founded. Production started with handmade pipes and exhaust systems, all crafted with an intense attention to detail, incredible level of craftsmanship, and high standard of performance.

Now, with a streamlined production and several years of experience and innovation under their belt, FMF has become an industry leader in exhaust systems, pipes, and products. Their reputation for crafting durable and high-quality products from premium materials has certainly helped FMF land that standing, but it’s not the only thing.

Racer-borne and racer-run, FMF has never forgotten why they got into the business in the first place, and their brand is so much more than just exhaust products. As a huge supporter of professional motorcycling and the lifestyle that comes with, FMF sponsors several race series and manufacturers an impressive casual line to give back to the community that has given so much to them. This dedication to the sport, along with the fact that their exhaust systems and parts are made in the U.S.A., from start to finish, are just some of the unique qualities that set FMF apart from the competition.

  • FMF Power Core IV S/A Silencer

    FMF Power Core IV S/A Silencer

    Chris in CA

    Should have bought this years ago!

    A little loud but I knew this from reading previous reviews, but it is okay as I am losing my hearing anyway. Bike has a little more pep now. Ease of installation was easy, just had an issue with the bracket that holds the rear of the exhaust in place, I had to do some bending on the bracket to make it fit correctly. Pipe weighs five pounds compared to the OEM exhaust that weighs 10 pounds! Ordered the pipe Saturday evening, figuring that it would be Thursday when it would show up, but came in Tuesday afternoon. Very happy with their customer service!

  • FMF Gold Series Pipe, "Gnarly Torque"

    FMF Gold Series Pipe, "Gnarly Torque"

    Aaron in WA

    Great bottom and mid range power for TPI

    Pipe was a little challenging to install but I believe it's because they intended the pipe to be much closer to the frame, tucked in. Overall the pipe is much closer which should help limit abuse and dents. The power is much better for the TPI and better resembled the torque and grunt my previous carbuerated KTM 300 had with the smoothness of throttle of the TPI. Perfect combination.

  • FMF Don Guard Straw Track Hat

    FMF Don Guard Straw Track Hat

    Chad in OH

    This straw hat straw hats amazingly well. I’ve never owned any other straw hats, but I find it hard to believe that they could out straw hat this straw hat. Freddy Mack Factory straw hats are simply incredible. I recommend this straw to everyone I see wearing a hat, even people that don’t wear hats. (I’ve only been questioned by police 3 times). Sometimes I go door to door and sing the praises of this hat to anyone that’ll listen. I’m like the Jehovah Witness of straw hats. I hope this review really helps in your tough decision as to which straw hat you should purchase.
