            The only way a total decat would over speed the turbo and therefore damage it would be if the standard waste gate wasn't big enough and then you'd get boost creep. I've never tested it so can't say for sure if it would be a problem or not.
            Why do you want to do a total decat? A good sports cat is going to cost you almost no horsepower compared to a decat.

              dont listen to people who say it will damage your turbo, been running no cat for over 2 years now and it is fine, never had any problems, just a smoother car, way better than a sports cat

                sports cat = £150 and no cat = £30.
