When you install what most would call a "turbo back" exhaust on your Duramax, you're not really getting a turbo back kit. Upgrade the last vital component for superior exhaust flow by replacing the stock turbo direct pipe with this ATLAS Series piece from AFE.

Optimize your LB7'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.

LEAK-FREE SEAL: CNC machined, heavy duty inlet flange and quality V-band flange are used for a complete 360 degree sealing surface at the turbo housing and exhaust system.

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.

Super comfy and pretty
Color: Black, Size: X-Large
Fit is nice and comfortable!!! Soft in the inside as well! It’s not huge but also doesn’t stick to me. You can literally wear it down (casual with jeans or shorts) or dress up (like I did for Mother’s Day with a nice skirt and jacket) Seems breathable enough for our California heat

Great buy. Love this shirt!
Color: Teal, Size: Medium
This shirt is so great. The color is absolutely stunning and vibrant! The material is so soft and comfortable. I use it as a casual work shirt with capri leggings, and stay comfortable all day. It definitely runs a bit large. I am short so it hangs very long but I like my shirts that way for work. I am usually somewhere between a small and a medium and I like a loose fit so I got a Medium. This was almost too big for me to wear, but I am making it work. I plan to buy this shirt in multiple colors and will get a small next time. For reference, I am 5"2', 126lbs, bra size 34 C.

Feels soft!
Color: Black, Size: 4X-Large
The fabric is great, as is the weight, fit, color. It covers the backside and doesn’t bulge around the hip. Would love to see it in several colors!

Really great quality and fit for the price
Color: Navy Blue, Size: Large
These tank tops are beautifully cut, the colors are great, the fabric is stretchy and comfortable and they don’t look at all cheap. A very welcome surprise that they exceeded expectations. I spend the entire summer in slim fit tanks and A-line skirts with a jean jacket or shirt over and ended up buying practically every color because I like them so much - can pair them with much more high end items and they don’t look out of place.
