I picked it up about month ago, paid too much compared to that price though. Easy install, about 2 hours start to finish. Sounds great also, louder than I thought it would be .. as far as power gain, can't notice any really, if anything it's after 5k rpm. Hope this helps.
Sorry about the quality I need a major engine bath also, this is the exact same one other than the color. Metal tubing, easy to install, oh ! one thing I had a problem with was the ecm rubs on the body behind the hood and makes a small squeek noise. I had to put some rubber pads on it to stop it.
