I think it was because of the exit size of my catylatic convertor, also in the other exhaust threads there is a link which I cannot post becuase I dont have enough posts yet, but it shows you how big of exhaust pipe you need for what horsepower levels. The car I drive is 140hp and it is on the border i believe for 2'' to 2 1/4'' pipe, and the way I drive my car 2'' should be perfect.
