I found the cybox decat was great for a typical Italian twincam engine gaining a raspier engine note and also a much freer revvy engine.
The cons for me were higher fuel consumption and very slightly down on performance compared to the cat.
This was fitted to a CF2 2.0ltr twinspark and tested over 6 months, worth it for the noise alone if you can live with a few less mpg's.
I am hanging on to the silenced decat for now and may fit it again sometime in the future as the car was a different animal, but it does seem to hit arounf 30 mpg now as opposed to mid 20's without the cat.
