Must have product
If you have a duramax, then as this to your list. Much easier and stronger than the stock valve cover bolts.

Sounds great
2 of 2 found this helpful I ordered this exhaust kit at noon on Thursday. It was at my house the next day! SMR you are awesome! This isn’t the easiest exhaust to install. I say that because it it by myself. The connections are very tight, so I lubed up the pipes to slide into each other and be able to maneuver them around. Also the hangers don’t exactly line up, but couple of them worked to keep it secure for now. I have a small welder that will fix all that. The kit came with everything needed and instructions were clear. Sounds great!!
