silly question maybe but, I have a twin turboed 416 making over 1000hp and im still running the stock 2 1/2 dual exhaust am I holding the motor back by not running dual 3"? im running no mufflers or cats just the stock resonators, my opinion is do I change the exhaust to maybe get 10-30hp when I wont even notice it? thanks fellas.

Expect a lot more than 30rwhp going up to twin 3".
Twin 3" is an absolute minimum requirement at your power level.

Agreed^ go 3" True Duals all the way.
