FMF – Gnarly Pipe

The FMF Gnarly Pipe is built for riders who like to push deep into the woods, hammer rocky climbs, and muscle through terrain that eats lighter pipes alive. Designed for 200cc to 500cc two-strokes, this pipe turns your bike into a torque monster — more pull at low rpm, smoother mid-range power, and that tractor-like grunt that gets you out of sketchy situations.

Made from super-strong 18-gauge steel, the Gnarly is tough enough to take real off-road abuse — rocks, logs, and crashes are just part of the ride. It’s electro-nickel plated for a durable, chip-resistant finish that won’t fade or rust, no matter how many muddy washes you slog through. O-rings are included, so installation is straightforward and airtight.

Why We Like It:
This is the pipe that saves your day when the trail gets ugly. It gives your two-stroke the kind of low-end torque you usually only find on big 4-strokes, making it easier to crawl over roots, rocks, and technical climbs without constantly clutching. It’s basically bulletproof and sounds awesome doing it.

Why It’ll Work for You:
The Gnarly Pipe helps your bike put power where you actually need it — down low. That means it pulls stronger at slow speeds, giving you more control in tight sections and better traction when things get slick. And because it’s built from heavy-duty steel with a nickel-plated finish, you can drop it, scrape it, and ride it hard without worrying about damage.

Variants / Options:
Fits most late-model 200cc–500cc two-stroke bikes. Direct bolt-on fit for off-road and enduro setups.

 

Key Features:

  • Focuses on low-end torque and bottom-to-mid power

  • Heavy-duty 18-gauge steel construction for extreme durability

  • Electro-nickel plated finish resists chips and discoloration

  • Built to handle off-road punishment and rough terrain

  • Includes O-rings for easy, tight installation

  • Ideal for 200cc–500cc two-stroke machines

Incredible Comfort
Size: Large, Color: Multicoloured F (5-pack)
Amazing; I’ll be ordering more. Super soft, lightweight, smooth under clothes, incredible comfort! Best underwear! I ordered these because I’m tired of underwear lines when wearing biker shorts/leggings. Other boy shorts were too long or the bottom hem too thick and both of those issues left lines around my upper leg. THESE are *just right* - perfect length and fit. No panty lines on close fitting pants, comfortable under other pants and dresses, great with jumpsuits, and fit well under slip shorts with dresses. NOTE: These take longer to dry, than similar clothes, in the dryer. No shrinking though. SIZE: I ordered these in size L and they fit perfectly. A little snug when first on but they loosened up. For reference I’m 5’4” tall, about 175#, carry my weight in my hips and backside,wear size L sweats/pajamas/loose pants, size 12 jeans.

Full coverage and full comfort
Size: XX-Large, Color: Multicoloured C (5-pack)
These boyshort underwear are a dream. They’re very soft, very stretchy, and very comfortable. They do not shrink when they’re washed. They’re heavy enough to make you feel like you have something covering you for discretion, but light enough to wear under any type of fabric. I have wide hips and I’m older so I don’t have a tight perky butt anymore. Most underwear tend to either ride up on me or become very uncomfortable. These stay where you put them. And they come all the way up to your waist so that there is no panty line whatsoever. The waist line is soft and comfortably. It does not dig in. They do not ride up and drive you crazy they stay where you put them. I would recommend them to anyone young or old. I have tried so many different styles and materials to find underwear that’s actually comfortable. These are the absolute best I have tried in five years. I just threw all the rest of them out.

Bamboo is an amazing fabric
Size: Large, Color: Multicoloured I (5-pack)
Comfy and soft . I’ve never worn boy shorts before so takes adjusting to. Legs roll sliding pants up but easy to adjust and smooth before zipping up then all day comfort. When I wear skirts or shorts they are perfect for that! I use to wear bike pants under skirts that don’t have to anymore. I like that they don’t creep up like regular underwear. I’m a new fan of bamboo fabric and bought briefs in bamboo as well.

The softest, stretchiest, perfect underwear!
Size: Large, Color: Multicoloured F (5-pack)
I have struggled for years to find underwear that didn't ride up. I like bamboo, but had the same problem with them. These Bamboo Cool Boyshorts not only solved my problem, but they are so soft and stretchy that it almost feels sensual pulling them on. They never ride up, roll down, they fit perfectly, and are always super comfortable. I even persuaded my husband to buy the men's version and he loves them too. And I should add, I never write reviews!

YES!
Size: Medium, Color: Multicoloured D (5-pack)
I don't give too many items 5 stars, but these are reorder worthy! I bought these a year ago, and am now going back for another 5 pack; not because my first order wore out, but because they are still SO great, I want more! These are my go to for under dresses, skirts, & flowy pants where I want full coverage, but no panty lines! AND bonus, sweat absorption. The leg openings are a tight when I first put them on, but they stay put and are very comfortable. I get my normal size
