so i was a bit scared at first because a lot of people have always had issues with aftermarket headers for these trucks, but i've heard of this and that brand since he's known for it is to make headers, i got my headers that didn't come with high temp paint or anything else so you have to paint or wrap them, they attach them directly and it didn't fit which meant a different problem than a couple of cuts that i did had to make one of the pipes.
