although I am a little bit away from this purchase I have pondered about the kits as well.
I want the scivion kit with a new pipe to allow for getting rid of stock placment. I will have to look into that.

 

While I do really like my setup... It is not currently a plug-n-play setup, yet. I believe as more people use it, and I get more time (currently out of the country), that it will become a viable choice for the 951. I would only advise going my route if you want to learn more about your car and the tuning process.
