Stef has the Capristo bypass valve kit on his F430, so could look at the difference. There is no doubt the bypass valves increase backpressure when closed, and that will increase temperatures back along the exhaust system. Lack of airflow could be a factor, too.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
