LG Street Headers... Finally got 'em on.

I finally got my LG Streets last week. I unpacked them and laid them out to see what all I get for my money.  I gotta say the finish on these headers is top notch.  The whole system, headers and x-pipe is highly polished and looking like a piece of art work.   It's a shame that all of that is under the car and can't be seen.  After a trip to the dealership for some gaskets, I coulddnt wait and had to install it ASAP.  Long story short the car sounds absolutely incredible now.  The idle is definitely more crisp and light acceleration is a little louder but the big difference is under aggressive acceleration or WOT. The car sounds absolutely incredible now (did i say that?). This is going to be fun trying to sneak by all the cops I see on my way in to work every day.  I had a few issues with the clamps supplied with the headers and the 02 sensor wires needing a little extension but other than that the install went fairly smooth and I love the end result.  Just had to share. 

how difficult was the install?
thanks in advance for any details
