Hey zero2sicksty, yes I have one on my GTS 6-speed. To install it, I just went to a shop by my house, it only cost me like 35 bucks and it was done the same day I took it in. If you wanted to do it yourself you would have to remove the alternator and have some special tools to remove the belt and stock pulley, I can't remember what they are, but they will tell in the instructions you will recieve in the kit. I would recommend that you get it done at a shop, but if you know enough about it and want to do it yourself all the power to you. With this new kit, I noticed much better throttle response and more horsepower. Most people I talked to about it said that they didn't really notice a power gain with this kit, but I definitely saw a small power gain. I did some research, and AEM claims that it gives about an 8 horsepower increase. The only conclusion that I thought of is that maybe you don't really see a hp gain if you have this kit on an auto...and it does look good under the hood, you have to close to see it because it's under part of the engine, but it looks good none the less. Hope I could help, later...peace.
