I would tend to disagree, a dual 2.5" can only support around 450fwhp before it starts to be an issue. Plus the sound of a 3" is much better, deeper all around and quieter around town. Ive had mine on for 3 summers of cruising and racing and I am so glad I dropped the coin and time for it when I did. My car runs pretty FN good for what it is and I know it would slow down a touch with a 2.5". Remember fuel injected cars do not rely on the "venturi effect" so having a larger exhaust doesnt kill performance, it may not help but there is no downside to oversizing it. In fact if there is a slim chance you will make over 400rwhp at some point why buy 2 exhaust systems?
This is mine, but im running Kooks 1-3/4" headers now. Again its fantastic and would not change a thing
