I'm going to install a set of Champion ported irons and was wondering if there is anyone who ports the oem intake who will leave the egr passage in place?
Also, how much of a restriction would an unported intake be with ported heads? I also have a stock unported throttle body with a power plate.
What I'm getting at is that I want to improve performance and still pass emissions once a year(removable cat.)
