The factory must have welded the header 2 degrees off. The slip on would not line up the secure 2 bolts in it. I was able to secure one. I had to wait 1 week for availablity so I was tired of waiting otherwise i would have sent back for another pipe. It will work. Looks good. Just upsetting I spent that much and its flawed. Everyone else should be fine though. Sounds good, light weight, and durable looking.
