Optimize your 01-04 LB7 GM diesel's airflow to improve throttle response with aFe's ATLAS 3" turbo down-pipe.Constructed from 3" mandrel bent steel tubing for maximum flow, the larger tube diameter and smooth transition bends allow increased airflow between your OE turbo and exhaust to reduce EGT's for quicker turbo spool times. The CNC machined heavy duty inlet flange with turbine gasket and V-band outlet flange ensure an OE-style, 360 degree sealing surface. Coated with a black finish, the ATLAS turbo down-pipe is wrapped with thermal header tape to reduce EGT's for improved performance and durability. Flow and Performance: The ATLAS turbo down-pipe is made from 3" mandrel bent steel tubing offering smoother transition bends for low turbulence to deliver quicker throttle response. Perfect Fit: The ATLAS turbo down-pipe is an upgrade to the OE down-pipe and utilizes the factory mounting locations for true bolt-on performance. Finish: This down pipe is coated with a black finish and wrapped in thermal header tape for better insulation. This reduces EGT's and under hood temperatures.

Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too.
Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.

Quality No Show Socks That Are Comfortable and Durable
Size: Large, Color: (100) White / White / Black
These Under Armour no show socks are great for everyday training and casual wear. The cotton blend feels comfortable and they stay in place throughout the day. Getting six pairs in a pack is solid value for a quality brand. They hold up well after multiple washes and the no show style works great with most athletic shoes. A reliable go-to sock.

Comfortable
Size: Large, Color: (001) Black / Black / White
I recently picked up a pair of Under Armour socks, and they’ve quickly become my go-to choice for daily wear and workouts. From the first wear, the fit felt snug and supportive without being too tight. The fabric is lightweight yet durable, and it does a great job wicking sweat — keeping my feet dry even during longer runs or intense gym sessions.
One of the things I appreciate most is the arch support and cushioning in the right places. It adds just enough padding where I need it, especially under the ball and heel of the foot, which makes a noticeable difference on days when I’m on my feet a lot. The socks also have a nice breathable mesh pattern that improves airflow.
