ok i have a flowmaster muffler now. i am thinking of changing my exhaust system completly. i want to know if i go with a full race header will the flex pipe still matter. i am thinking of doing a 2.5 focus sport flex with the 2.5 True Bendz cat back, and borla muffler. ( my flowmaster is very loud). if i start with the flex pipe first will it bolt onto the stock pipe??

Focus Sport flex is only 2 1/4 inches. The flex will bolt onto the stock pipe

oh, it says it's 2.5 but maybe that was the cosworth. i will get the 2.5 which ever it is.

The cosworth flex will not bolt up. It was designed for a different motor than the
zetec.

trubendz and mcnews offer a 2.5 flex though.
