Description
Big Gun 20-22 Yamaha YZ 450F EXO Aluminum Full System ExhaustEXO Series came about from a realization of the need for a bigger and better muffler that could handle the huge demands of the larger, more powerful MX motors. The EXO Series is our ground up approach at just that. A unique hexagon shaped aluminum muffler and stainless steel coned inlet allow for significantly more volume, delivering a louder but tolerable deep sound while also decreasing heat.

No show but stays on
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.

I like the ankle length, they don’t slip.
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I love these socks, they are thick enough to not be scratchy, thin enough to be cool and breathable.

Fit great
Size: Large, Color: (100) White / White / Halo Gray
Been a couple of months and they seem to be holding up nicely. Real picky about fit of socks and these fit well. They are very thin but very comfortable.

Always a win
Size: Large, Color: (001) Black / Black / Castlerock
Under armor is always a win! Comfortable, no peeling, true to size, no squeezing around the arch of foot & affordable.
