Yeah, they sound just like headers. Like I said, the cat back situation really bothers me. I don't know if mine is different, but i had to use a jack on the driver's side, take the passenger side loose, and then push it up like almost 2 inches to get it to bolt up. It'll make it to the exhaust shop that way though, so it's not going to be that big of a deal. I just wish it would have fit better.
