In my experience, headers make no difference below 3000 rpms over the stock exhaust setup. Also, if that's a 4.8 or 5.3 under the hood, it's my opinion that a 3" y pipe is simply too big. Even with a 6.0 I have preferred a 2.5 inch Y pipe over a 3". It's a better compromise between exhaust velocity and top end power in my opinion.
