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.

Stylish
Size: Large, Color: White
This Alimens & Gentle Oxford shirt is honestly a great addition to any wardrobe and completely exceeded my expectations ⭐⭐⭐⭐⭐. The material thickness is spot on. It’s not too thin and not heavy either, which makes it perfect for both work and casual wear. The fabric feels sturdy and well structured without being stiff or uncomfortable.
The style is clean, classic, and versatile. It looks sharp enough for business or office settings, but you can easily dress it down for a more casual look. The white color is crisp and polished, and the cut gives it a modern, put together appearance without feeling too formal.
Quality really stands out with this shirt. The stitching is neat, the buttons are secure, and everything feels well made. It holds its shape nicely even after wearing it all day, and it doesn’t feel like one of those shirts that loses structure after a few washes.
Comfort is another big win. The stretch in the fabric makes a noticeable difference, especially when moving around, sitting, or reaching. It feels flexible and breathable, and you don’t feel restricted at all. It’s the kind of shirt you can wear from morning to night without feeling uncomfortable.
Wrinkle resistance is impressive. Even after a long day or sitting for hours, it still looks fairly smooth and presentable. A quick hang or light touch up is all it needs, which is great if you’re trying to save time.
Value for money is excellent. For the price, you’re getting a stylish, comfortable, and well made shirt that easily competes with much more expensive brands. It looks professional, feels great, and performs well.
Overall this shirt checks all the boxes. Great material, sharp style, solid quality, comfortable fit, and very good wrinkle resistance. I’d definitely recommend it and would happily buy more in different colors.

Work casual shirt that travels well:
Size: Large, Color: Dusty Blue, Size: Large, Color: Dusty Blue
This shirt runs true to size with a bit of room for more. The material is a bit stretchy which helps keep the shirt looking great without major wrinkles. The shirt itself is comfortable and feels like it'd last through many washes and the care instructions are fairly simple (cold wash and low dryer). This particular color is unusual and compliments many outfits.
Given the quality, this is a high value item. Just go easy with the iron.
