Valvetronic BMW G8x M3 / M4 Valved Sport Exhaust System*SYSTEMS CURRENTLY IN STOCK & READY TO SHIP!* Besides the quite strange grille setup, the G80 is a killer new M car, but like most, the sound is lacking. The Factory exhaust for the New G80 G82 BMW M3 4 does not deliver the goods. We fix that with our single 3. 5 inch mid pipe. This mid pipe incorporates an equal length design that allows for a very enjoyable high pitch sound experience without having to modify your OEM rear section. This mid pipe

Not polyester! Thank you UA!
I never realized shopping for cotton socks in 2024 would be so difficult. Luckily I found these, and all the other Under Armour cotton socks and they are the best. I cannot wear polyester, and these only have like 1%. I didn't realize our cotton is being replaced by polyester, and I don't like it. Bath towels don't work anymore either... I need my cotton socks and towels, I love incandescent light bulbs, I'll always have a gas powered mower and leaf blower. Also butterfinger should've never their recipe. Just sayin...

Great sock for everyday
Size: Large, Color: Black/Gray (6 Pairs)
So these are awesome but they are slightly thinner than older versions, shorter too. Just FYI if you a long time UA customer. If you have never had their socks, I love them personally and only like one other brand better. They aren’t overly thick and they allow your feet to breath. I never have sweaty feet in these even in my warm boots. I also like that they don’t cut into my feet or get holes in the toes over long terms. The only reason I’ve thrown these out has been fraying near the ankle or someone (kids) thieving them.
