Optimizing your y-pipe is simply having your y-pipe pulled off the car and grinding out the the intersection where all three tubes come together. Stock, this chamber is pinched pretty tight allowing minimal airflow. With a little grinding, this area is opened up drastically. I felt 3 hp down low AND up top in the rpm range.
Some might argue that this process is better than buying an aftermarket y-pipe.
