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.

Kept our dog busy!
Color: Navy Blue, Color: Navy Blue
We have a 4 month old corgi and he is obsessed with this toy. The puzzle pieces move really easily so they are able to get into it but also create enough of a puzzle for them to move around.

Challenging for my experienced puzzle players, sturdy all in one.
Color: Navy Blue
My girls love this treat puzzle; it is not for a first timer. My dogs have several of these and they cannot get the hand of spinning the light blue circle to move the small red covers. It is a challenge and that is what they need to give me some me time.

Keeps my dog busy for a bit
Color: Navy Blue
I don't fill the hard to open spots yet, he's just figuring it out. It does keep his attention. It's a little small for a big dog (100lb Lab), prob better for a small dog. He has a hard time with the little trays. Definitely worth trying out. I wanted an inexpensive puzzle toy to try first, in case he didn't like it or couldn't figure it out.

Great Puzzle, My Dog Loves It!
Color: Navy Blue
It’s perfect! My dog loves it and i’m very satisfied with this purchase. The outside of the box did come sticky, which was kind of weird. Overall it’s great!
