Great Product
Everything fit like a glove aside from hose. The 5/8” hose provided is not very long. Had to obtain from auto parts store to complete neatly. Also missing gasket for oil side of turbo. Had to obtain from dealership. Great product aside from these issues.
Great product. Good price for an aluminum cover with all the extras. Fill, drain and fluid level view window are great options. Top notch product.

Not for a novice!!!
05 LLY Duramax. I soaked bolts for days in a penetration oil, used heat and had a bolt break off in turbo, which made install miserable. I also did mine while transmission was out. This would not be easy with transmission attached, just a FYI. Great product, decent shipping, but not sure what the bolts that came with it are for, because they were not even close to stock up pipe bolts. Had to retain stock mounting hardware!!

Like stock!
I was surprised when I removed the DPF/SCR and replaced it with a straight pipe with a high flow muffler… and it was quiet. But I don’t have to worry about getting pulled over. Easy install, very straightforward. Would buy again. Shipped fast! But if you want louder pipes, consider the straight pipe.
The exhaust sounds amazing. And very easy to install. Only complaint would be packaging. UPS destroys the box when delivered, if there were better Cushioning within the box, less likely to be damaged.
Worry-Free Purchase
