2017-2025 GM 6.6L Duramax High-Flow 304 Stainless Steel Down Pipe

It really was a shame hiding this behind the engine.. I will definitely be ordering the up pipes in the future!

Very well constructed, fit like a glove.

The cast and machined flanges are of quality I wouldn't want to hide under a clamp. They blend well with the pipe and would appear to have good flow characteristics. Everything fit right up as it should. I did end up needing to add a third hose clamp to the middle of the wrap to keep it from sliding down the pipe.

The Product delivered fast and efficiently. The Down Pipe had tight fit but once you get it past the transmission dipstick the rest is easy. Everything connected how it should and I am extremely happy with the purchase. The only downside is that I could only get one side of the transmission dipstick tighten back up, but with the bigger size of the Down Pipe the dipstick is in there solid. I could have bent the bracket somewhere along the line during removal or installation. I would recommend this product to anyone wanting a after market Down Pipe for the LBZ Duramax.
