Quality product, however had a little trouble...
Quality product, however had a little trouble with the tail pipe and over the axle pipe hangers not being bent properly to make fit easy. Had to bend and test fit several times.

Great product
It was really easy to install and fit like a glove. I'm running checks on mileage and it had increased 3 mpg

No Downpipe
The description states that this kit comes with a 4in downpipe however it did not come with this kit. Now I will either have to buy one or wait to receive the one that supposed to come with this kit.

This product states it is a 5 inch downpipe back with 4 inch down pipe. Does that mean I need to order a 4 inch down pipe too? Or will it bolt to my stock downpipe??

This system includes a 4"" downpipe.

In the description it says with 4 inch down pipe, does it come with a down pipe or does it only work with a 4inch downpipe??

This unit would not include the downpipe, or direct pipe as its called on Duramax applications. The kit connects to the factory direct pipe's V-band clamp, then jumps up to the 5"" system. - AW
