Titanium coating is really easy to scratch during installation. There is a special note in the instructions that say if you need warranty work, and they are returned scratched, you will be charged for recoating. Also there is weld splatter on the inside of most every header tube and the coating is put on over the splatter. They are very good quality when compared to other headers I have dealt with.
It was an easy install and it looks great. I was really disapointed in the sound. It is actually quieter than my stock system if thats possible. The system came with a muffler delete pipe but I chose to use the muffler that came with it because it is far less restrictive than the stock muffler. I wanted a system with some nice throaty sound but it was not the case.
