scrupul0us Posted October 1, 2015 Share Posted October 1, 2015 When I had my 00' cougar, there were precats in the stock exhaust manifolds (v6) which I removed before installing my exhaust. Was wondering if the 2.5i had anything similar and if so, any experiences with gutting them (performance, MIL issues, etc) Thank you =) This is my signature, there are many like it but this one is mine Link to comment Share on other sites More sharing options...
