FMF – Powercore 4 Hex Muffler (Beta)

The FMF Powercore 4 Hex Muffler is built for Beta riders who want better throttle response and stronger pull without adding excess noise. Its compact hex-shaped design uses a multi-stage internal core and precision-packed materials to improve power through the entire RPM range while keeping sound levels controlled for off-road and race environments. Lighter than stock and designed to handle real trail abuse, it’s a practical upgrade for riders who want smoother performance and dependable durability.

Why We Like It

It gives the bike a cleaner, stronger feel without turning the exhaust note into something obnoxious. Power delivery improves everywhere—from slow, technical sections to long uphill pulls—and the build quality holds up well to off-road use. The spark arrestor is already built in, so it’s ready for trail systems and race events that require it.

Why It’ll Work for You

If you want better performance with manageable sound levels, this muffler makes the bike easier to ride. It broadens the power, trims weight compared to stock, and keeps you compliant with USFS sound regulations. It’s a simple bolt-on upgrade that helps the bike respond quicker and pull more consistently without extra tuning.

Great for chewers
Color: Knuckle Bone, Size: XX-Large
I have a 13 month old 56 lb boxer/rottie mix who is a medium chewer and this bone is great for him. No splintering, doesn't make a mess, and hard enough to make him work without any danger of him breaking teeth, getting cut, or choking. We gave it to him a couple of weeks ago and based on wear I'm confident it will last him a long time (many months at least). I was a little hesitant about giving my animal a product that contained nylon, but after a scary experience giving a rawhide bone to a previous foster dog, I was told this was a much safer option and now I agree. This bone is very dense and very hard, so it makes an awful noise when my dog drops it on my hardwood floor. We are also careful to make sure he doesn't drop it on our bare toes, because that would be quite unpleasant. Be aware that the chewed edges also get really rough because of the way the bone wears, so they can become a magnet for dog hairs or fabric threads. This hasn't been a problem for us (we just encourage our pup to chew it on his bed and take it away from him when we are watching a movie so the noise isn't bothersome), but it is good to know. Update: We've had Winston for 5 months now and in that time he has gained 5 lbs of muscle. He loves his Nylabone! It is still going strong and I think he will be able to use this well through his one year adoptiversary. The only issue we have with this bone is that the edges can get sharp and sometimes will cut his mouth. He doesn't notice and just wants to keep chewing, but we usually take the bone away at that point for a bit. My boyfriend has taken the bone and used a power sander on it a few times now to remove all the sharp edges. We only have to to in once every couple of months but it makes a big difference.

The best toy my dog has
Color: Monster Bone, Size: XX-Large
Our lab mix is a very ambitious chewer - forget retrieving... he seems to think his "job" in life is to destroy things with his teeth. He's very methodical about it; he'll chew and chew and chew, targeting the object's weakest points, until all that remains is a littering of coin-sized remnants. He even started to make progress on his heavy duty black Kong within about a week. By the time he was about 8 months old, we figured out that the only toys he can be left alone with are the ones made by Nylabone. He has all their models: dinosaurs, rings, small bones, and branches. These Nylabone toys are a hard plastic that chips off in tiny little shards. He's happy because he feels like he's making progress (even though it takes him a long time to do so) and we're happy because the toys last a relatively long time and he can't swallow anything that might hurt him. He does leave tiny plastic shavings on the carpet, but we have to vacuum a lot anyways because of his fur, so it's not a big deal. Of all his Nylabone toys, this is the best (and probably his favorite of the bunch). He really likes the size - just right for him to prance around with and show off. Although he's had it for four months, it's still smooth enough in the middle that we can hold it for him comfortably, and it's retained its original shape (unlike dinosaur and branch). If we could just train him not to drop this on our feet when he wants attention(it weighs a few pounds and has gotten a bit pokey on the ends)this would be the perfect toy.

Cute squeaky toy, good price.
Size: Pack of 3, Color: Mini Loofa
These little squeaky toys are one of my yorkie pups favorite. Being latex they are last longer than the material ones. Good price for the 3 pack.
