Pretty easy installation. Make sure the flange bolts fit the threads before installation, I had to re-tap the threads due to the Crome.

The installation was difficult due to the location of the bolts. I strongly recommend looking into catalytic convertors because the OEM cat's will not fit, and it is illegal to alter them to fit. I had a lot of difficulty finding a place to install new ones and get it up to code. I was not aware of this going into it. The headers themselves are a good upgrade, but required a lot of extra work.
