Just wondering is it worth it to remove the pinched stock y pipe and replacing it with a true y pipe and keeping the same diameter exhaust pipe for better flow. Thanks.

I cut off my Y pipe and welded 3 inch stainless steel dual exhaust with 4 inch tips coming out the back. Seen a difference right away. More throttle response and even more with CAI. Stock Y pipe, you can see the both 2 1/2 in pipes crushed in a 3 in pipe. Can you say She needs air flow.
